American football is a sport played between two teams of eleven with the objective of scoring points by advancing the ball into the opposing team's end zone. Known in the United States as football, it may also be referred to informally as gridiron. The ball can be advanced by running with it or throwing it to a teammate. Points can be scored by carrying the ball over the opponent's goal line, catching a pass thrown over that goal line, kicking the ball through the opponent's goal posts or tackling an opposing ball carrier in his own end zone.

In the United States, the major forms are high school football, college football and professional football. Each of these three are played under slightly different rules. High school football is governed by the National Federation of State High School Associations, while college football by the National Collegiate Athletic Association and National Association of Intercollegiate Athletics. The major league for professional football is the National Football League (NFL). Other minor professional leagues also exist in the U.S., and may also have slightly different rules from those of the NFL.

The sport is also played in Europe, Japan, Mexico, and several other countries. The International Federation of American Football acts as an international governing body for the sport, but the organization has little standing in the United States.

American football is closely related to Canadian football but with some differences in rules and the field. Both sports can be traced to early versions of association football and rugby football.

History

The history of American football can be traced to early versions of rugby football and association football. Both games have their origins in varieties of football played in the United Kingdom in the mid-19th century, in which a ball is kicked at a goal and/or run over a line. Many games known as "football" were being played at colleges and universities in the United States in the first half of the 19th century.

American football resulted from several major divergences from rugby football, most notably the rule changes instituted by Walter Camp, considered the "Father of American Football". Among these important changes were the introduction of the line of scrimmage and of down-and-distance rules. In the late 19th and early 20th centuries, game play developments by college coaches such as Eddie Cochems, Amos Alonzo Stagg, Knute Rockne, and Glenn "Pop" Warner helped take advantage of the newly introduced forward pass.

The popularity of collegiate football grew as it became the dominant version of the sport for the first half of the twentieth century. Bowl games, a college football tradition, attracted a national audience for collegiate teams. Bolstered by fierce rivalries, college football still holds widespread appeal in the US.

The origin of professional football can be traced back to 1892, with William "Pudge" Heffelfinger's $500 contract to play in a game for the Allegheny Athletic Association against the Pittsburgh Athletic Club. The first Professional "league" was the Ohio League, formed in 1903, and the first Professional Football championship game was between the Buffalo Prospects and the Canton Bulldogs in 1919. In 1920, the American Professional Football Association was formed. The first game was played in Dayton, Ohio on October 3, 1920 with the host Triangles defeating the Columbus Panhandles 14–0. The league changed its name to the National Football League (NFL) two years later, and eventually became the major league of American football. Initially a sport of Midwestern industrial towns in the United States, professional football eventually became a national phenomenon. Football's increasing popularity is usually traced to the 1958 NFL Championship Game, a contest that has been dubbed the "Greatest Game Ever Played". A rival league to the NFL, the American Football League (AFL), began play in 1960; the pressure it put on the senior league led to a merger between the two leagues and the creation of the Super Bowl, which has become the most watched television event in the United States on an annual basis.

Rules

Field and players

American football is played on a field . The longer boundary lines are sidelines, while the shorter boundary lines are end lines. Sidelines and end lines are out of bounds. Near each end of the field is a goal line; they are apart. A scoring area called an end zone extends beyond each goal line to each end line. The end zone includes the goal line but not the end line. While the playing field is effectively flat, it is common for a field to be built with a slight crown—with the middle of the field higher than the sides—to allow water to drain from the field.

Yard lines cross the field every , and are numbered every 10 yards from each goal line to the 50-yard line, or midfield (similar to a typical rugby league field). Two rows of short lines, known as inbounds lines or hash marks, run at 1-yard (91.4 cm) intervals perpendicular to the sidelines near the middle of the field. All plays start with the ball on or between the hash marks. Because of the arrangement of the lines, the field is occasionally referred to as a gridiron in a reference to the cooking grill with a similar pattern of lines.

At the back of each end zone are two goalposts (also called uprights) connected by a crossbar from the ground. For high skill levels, the posts are apart. For lower skill levels, these are widened to .

Each team has 11 players on the field at a time. Usually there are many more players off the field (an NFL team has a limit of 53 players on their roster, all of which can be dressed for a game). However, teams may substitute for any or all of their players during the breaks between plays. As a result, players have very specialized roles and are divided into three separate units: the offense, the defense and the special teams. It is rare for all team members to participate in a given game, as some roles have little utility beyond that of an injury substitute.

Start of halves

Similarly to association football, the game begins with a coin toss to determine which team will kick off to begin the game and which goal each team will defend. Unlike association football though, the options are presented again to start the second half; the choices for the first half do not automatically determine the start of the second half. The referee conducts the coin toss with the captains (or sometimes coaches) of the opposing teams. The team that wins the coin toss has three options: # They may choose whether to kick or receive the opening kickoff. # They may choose which goal to defend. # They may choose to defer the first choice to the other team and have first choice to start the second half. Whatever the first team chooses, the second team has the option on the other choice (for example, if the first team elects to receive at the start of the game, the second team can decide which goal to defend).

At the start of the second half, the options to kick, receive, or choose a goal to defend are presented to the captains again. The team which did not choose first to start the first half (or which deferred its privilege to choose first) now gets first choice of options.

Game duration

A standard football game consists of four 15-minute quarters (12-minute quarters in high-school football and often shorter at lower levels), with a 12-minute half-time intermission after the second quarter. At all levels, a down (play) that begins before time expires is allowed to continue until its completion, even after the clock reaches zero. The clock is also stopped after certain plays, therefore, a game can last considerably longer (often more than three hours in real time), and if a game is broadcast on television, TV timeouts are taken at certain intervals of the game to broadcast commercials outside of game action. If an NFL game is tied after four quarters, the teams play an additional period lasting up to 15 minutes. In a regular season NFL overtime game, the first team that scores wins, even if the other team does not get a possession; this is referred to as sudden death. However, in a post-season NFL game during the playoffs, if the first team with possession scores only a field goal, the other team is allowed the opportunity to match or better this score. This rule only affects playoff games in overtime in which the first team with possession scores a field goal: if the first team with possession scores a touchdown, the sudden death rules take effect. In a regular-season NFL game, if neither team scores in overtime, the game is a tie. In an NFL playoff game, additional overtime periods are played, as needed, to determine a winner. College overtime rules are more complicated.

Advancing the ball

Advancing the ball in American football resembles the six-tackle rule and the play-the-ball in rugby league. The team that takes possession of the ball (the offense) has four attempts, called downs, in which to advance the ball at least toward their opponent's (the defense's) end zone. When the offense succeeds in gaining at least 10 yards, it gets a first down, meaning the team starts a new set of four downs to gain yet another 10 yards or to score. If the offense fails to gain a first down (10 yards) after four downs, the other team gets possession of the ball at the point where the fourth down ended, beginning with their first down to advance the ball in the opposite direction.

Except at the beginning of halves and after scores, the ball is always put into play by a snap. Offensive players line up facing defensive players at the line of scrimmage (the position on the field where the play begins). One offensive player, the center, then passes (or "snaps") the ball backwards between his legs to a teammate behind him, usually the quarterback.

Players can then advance the ball in two ways: # By running with the ball, also known as rushing. # By throwing the ball to a teammate, known as a pass or as passing the football. If the pass is thrown down-field, it is known as a forward pass. The forward pass is a key factor distinguishing American and Canadian football from other football sports. The offense can throw the ball forward only once during a down and only from behind the line of scrimmage. However, the ball can be handed-off to another player or thrown, pitched, or tossed sideways or backwards (a lateral pass) at any time.

A down ends, and the ball becomes dead, after any of the following:

The player with the ball is forced to the ground (a tackle) or has his forward progress halted by members of the other team (as determined by an official).

A forward pass flies beyond the dimensions of the field (out of bounds) or touches the ground before it is caught. This is known as an incomplete pass. The ball is returned to the most recent line of scrimmage for the next down.

The ball or the player with the ball goes out of bounds.

A team scores.

Officials blow a whistle to notify players that the down is over.

Before each down, each team chooses a play, or coordinated movements and actions, that the players should follow on a down. Sometimes, downs themselves are referred to as "plays."

Change of possession

The offense maintains possession of the ball unless one of the following things occurs:

The team fails to get a first down— i.e., in four downs they fail to move the ball past a line 10 yards ahead of where they got their last first down. The defensive team takes over the ball at the spot where the 4th-down play ends. A change of possession in this manner is commonly called a turnover on downs.

The offense scores a touchdown or field goal. The team that scored then kicks the ball to the other team in a special play called a kickoff.

The offense punts the ball to the defense. A punt is a kick in which a player drops the ball and kicks it before it hits the ground. Punts are nearly always made on fourth down, when the offensive team does not want to risk giving up the ball to the other team at its current spot on the field (through a failed attempt to make a first down) and feels it is too far from the other team's goal post to attempt a field goal.

A defensive player catches a forward pass. This is called an interception, and the player who makes the interception can run with the ball until he is tackled, forced out of bounds, or scores.

An offensive player drops the ball (a fumble) and a defensive player picks it up. As with interceptions, a player recovering a fumble can run with the ball until tackled, forced out of bounds, or scoring. Passes that are thrown either backwards or parallel with the line of scrimmage (lateral passes) that are not caught do not cause the down to end as incomplete forward passes do; instead the ball is still live as if it had been fumbled. Lost fumbles and interceptions are together known as turnovers.

The offensive team misses a field goal attempt. The defensive team gets the ball at the spot where the previous play began (or, in the NFL, at the spot of the kick). If the unsuccessful kick was attempted from within of the end zone, the other team gets the ball at its own 20 yard line (that is, 20 yards from the end zone). If a field goal is missed or blocked and the ball remains in the field of play, a defensive player may pick up the ball and attempt to advance it.

While in his own end zone, an offensive ball carrier is tackled, forced out of bounds, loses the ball out of bounds, or the offense commits certain fouls in the end zone. This fairly rare occurrence is called a safety.

An offensive ball carrier fumbles the ball forward into the opposing end zone, and then the ball goes out of bounds. This extremely rare occurrence leads to a touchback, with the ball going over to the opposing team at their 20 yard line (Note that touchbacks during non-offensive special teams plays, such as punts and kickoffs, are quite common).

Scoring

A team scores points by the following plays: A touchdown (TD) is worth 6 points. It is scored when a player runs the ball into or catches a pass in his opponent's end zone. A touchdown is analogous to a try in rugby. Unlike rugby, a player does not have to touch the ball to the ground to score; a touchdown is scored any time a player has possession of the ball while any part of the ball is beyond the vertical plane created by the leading edge of the opponent's goal line stripe (the stripe itself is a part of the end zone).

After a touchdown, the scoring team attempts a try (which is also analogous to the conversion in rugby). The ball is placed at the other team's line (the line in the NFL). The team can attempt to kick it through the goalposts (over the crossbar and between the uprights) in the manner of a field goal for 1 point (an extra point or point-after touchdown (PAT)), or run or pass it into the end zone in the manner of a touchdown for 2 points (a two-point conversion). In college football, if the defense intercepts or recovers a fumble during a one or two point conversion attempt and returns it to the opposing end zone, the defensive team is awarded the two points.

A field goal (FG) is worth 3 points, and it is scored by kicking the ball through the goalposts defended by the opposition. Field goals may be place kicked (kicked when the ball is held vertically against the ground by a teammate) or drop kicked (extremely uncommon in the modern game due to the better accuracy of place kicks, with only two successful drop kicks in sixty-plus years in the NFL). A field goal is usually attempted on fourth down instead of a punt when the ball is close enough to the opponent's goalposts, or, when there is little or no time left to otherwise score. A safety, worth 2 points, is scored by the opposing team when the team in possession at the end of a down is responsible for the ball becoming dead behind its own goal line. For instance, a safety is scored by the defense if an offensive player is tackled, goes out of bounds, or fumbles the ball out of bounds in his own end zone. Safeties are relatively rare. Note that, though even more rare, the team initially on offense during a down can score a safety if a player of the original defense gains possession of the ball in front of his own goal line and then carries the ball or fumbles it into his own end zone where it becomes dead. However, if the ball becomes dead behind the goal line of the team in possession and its opponent is responsible for the ball being there (for instance, if the defense intercepts a forward pass in its own end zone and the ball becomes dead before the ball is advanced out of the end zone) it is a touchback: no points are scored and the team last in possession keeps possession with a first down at its own 20 yard line. In amateur football, in the extremely rare instance that a safety is scored on a try, it is worth only 1 point.

Kickoffs and free kicks

Each half begins with a kickoff. Teams also kick off after scoring touchdowns and field goals. The ball is kicked using a kicking tee from the team's own line in the NFL and college football (as of the 2007 season). The other team's kick returner tries to catch the ball and advance it as far as possible. Where he is stopped is the point where the offense will begin its drive, or series of offensive plays. If the kick returner catches the ball in his own end zone, he can either run with the ball, or elect for a touchback by kneeling in the end zone, in which case the receiving team then starts its offensive drive from its own 20 yard line. A touchback also occurs when the kick goes out-of-bounds in the end zone. (Punts and turnovers in the end zone can also result in a touchback). A kickoff that goes out-of-bounds anywhere other than the end zone before being touched by the receiving team is a foul, and the ball will be placed within the hash marks of the yard line where it went out of bounds, or from the kickoff spot, depending on which is more advantageous to the receiving team. Unlike with punts, once a kickoff goes 10 yards and the ball has hit the ground, it can be recovered by the kicking team. A team, especially one who is losing, can try to take advantage of this by attempting an onside kick.

After safeties, the team that gave up the points must free kick the ball to the other team from its own 20 yard line.

Penalties

Fouls (a type of rule violation) are punished with penalties against the offending team. Most penalties result in moving the football towards the offending team's end zone. If the penalty would move the ball more than half the distance towards the offender's end zone, the penalty becomes half the distance to the goal instead of its normal value.

Most penalties result in replaying the down. Some defensive penalties give the offense an automatic first down. Conversely, some offensive penalties result in loss of a down (loss of the right to repeat the down). If a penalty gives the offensive team enough yardage to gain a first down, they get a first down, as usual. The only penalty that results in points is if a team on offense commits a certain fouls, such as holding, in its own end zone, which results in a safety.

If a foul occurs during a down (after the play has begun), the down is allowed to continue and an official throws a yellow penalty flag near the spot of the foul. When the down ends, the team that did not commit the foul has the option of accepting the penalty, or declining the penalty and accepting the result of the down.

Variations

Limited contact

* touch football. A play ends when a defender touches the ball carrier (sometimes with two hands).

* flag football. A play ends when a defender removes a designated token ("flag") worn by the ball carrier.

* Wrap. A play ends when a defender wraps his arms round the ball carrier.

Fewer players

*nine-man football

*eight-man football

*six-man football

Smaller field

: The Arena Football League is a league that plays eight-man football, but also plays indoors and on a much smaller playing surface with rule changes to encourage a much more offensive game.

Catch and Run

: In this game, the children split into two teams and line up at opposite sides of the playing field. One side throws the ball to the other side. If the opposing team catches the ball, that player tries to run to the throwing teams touchdown without being tagged/tackled. If no one catches the ball or if the player is tagged/tackled, then that team has to throw the ball to the opposing team. This repeats until time runs out or the players decide to quit.

Players

Most football players have highly specialized roles. At the college and NFL levels, most play only offense or only defense.

Offense

The offensive line (OL) consists of five players whose job is to protect the passer and clear the way for runners by blocking members of the defense. The lineman in the middle is the center. Outside the center are the guards, and outside them are the tackles. Except for the center, who snaps the ball to one of the backs, offensive linemen generally do not handle the ball.

The quarterback (QB) receives the snap from the center on most plays. He then hands or tosses it to a running back, throws it to a receiver or runs with it himself. The quarterback is the leader of the offense and calls the plays that are signaled to him from the sidelines.

Running backs (RB) line up behind or beside the QB and specialize in running with the ball. They also block, catch passes and, on rare occasions, pass the ball to others or even receive the snap. If a team has two running backs in the game, usually one will be a halfback (HB) (or tailback (TB)), who is more likely to run with the ball, and the other will usually be a fullback (FB), who is more likely to block.

Wide receivers (WR) line up near the sidelines. They specialize in catching passes, though they also block for running plays or downfield after another receiver makes a catch.

Tight ends (TE) line up next to the offensive line. They can either play like wide receivers (catch passes) or like offensive linemen (protect the QB or create spaces for runners). Sometimes an offensive lineman takes the tight end position and is referred to as a tackle eligible.

At least seven players must line up on the line of scrimmage on every offensive play. The other players may line up anywhere behind the line. The exact number of running backs, wide receivers and tight ends may differ on any given play. For example, if the team needs only one yard, it may use three tight ends, two running backs and no wide receivers. On the other hand, if it needs 20 yards, it may replace all of its running backs and tight ends with wide receivers.

Defense

In contrast to members of the offense, the rules of professional football (NFL Rulebook) and American college football (NCAA Rulebook) do not specify starting position, movement, or coverage zones for members of the defensive team, except that they must be in the defensive zone at the start of play. The positions, movements and responsibilities of all defensive players are assigned by the team by selection of certain coverages, or patterns of placement and assignment of responsibilities. The positional roles are customary. These roles have varied over the history of American football. The following are customary defensive positions used in many coverages in modern American football.

The defensive line consists of three to six players who line up immediately across from the offensive line. They try to occupy the offensive linemen in order to free up the linebackers, disrupt the backfield (behind the offensive line) of the offense, and tackle the running back if he has the ball before he can gain yardage or the quarterback before he can throw or pass the ball. They are the first line of defense.

Behind the defensive line are the linebackers. They line up between the defensive line and defensive backs and may either rush the quarterback or cover potential receivers.

The last line of defense is known as the secondary, comprising at least three players who line up as defensive backs, who are either cornerbacks or safeties. They cover the receivers and try to stop pass completions. They occasionally rush the quarterback.

Special teams

The units of players who handle kicking plays are known as special teams. Three important special-teams players are the punter, who handles punts, the placekicker or kicker, who kicks off and attempts field goals and extra points, and the long snapper, who snaps the ball for extra points, field goals, and punts. Also included on special teams are the returners. These players return punts or kickoffs and try to get in good field position. These players can also score touchdowns.

Uniform numbering

In the NFL, ranges of uniform numbers are (usually) reserved for certain positions: 1–19: Quarterbacks, punters and placekickers 20–49: Running backs and defensive backs 50–79: Offensive and defensive linemen 10–19, 80–89: Wide receivers 40–49, 80–89: Tight ends 50–59, 90–99: Linebackers and defensive linemen (90–99) Players who switch positions in their career can keep their number if they played their prior position for at least a year and move from a position that is eligible to receive passes to another eligible position, or if he is moving from one ineligible position to another ineligible position.

NCAA and high school rules specify only that offensive linemen must have numbers in the 50–79 range, but the NCAA "strongly recommends" that quarterbacks and running backs have numbers below 50 and wide receivers numbers above 79. This helps officials, as it means that numbers 50 to 79 are ineligible receivers, or players that may not receive a forward pass (except in the rare instance when a Tackle lines up as the outermost lineman on his side of the line and the officials are notified that he will be an eligible receiver for that particular play). There are no numbering restrictions on defensive players in the NCAA, other than that a team may not have two players on the field at the same time with the same jersey number.

Basic strategy

Because the game stops after every down, giving teams a chance to call a new play, strategy plays a major role in football. Each team has a playbook of dozens to hundreds of plays. Ideally, each play is a scripted, strategically sound team-coordinated endeavor. Some plays are very safe; they are likely to get only a few yards. Other plays have the potential for long gains but at a greater risk of a loss of yardage or a turnover.

Generally speaking, rushing plays are less risky than passing plays. However, there are relatively safe passing plays and risky running plays. To deceive the other team, some passing plays are designed to resemble running plays and vice versa. These are referred to as play-action passes and draws, respectively. There are many trick or gadget plays, such as when a team lines up as if it intends to punt and then tries to run or pass for a first down. Such high-risk plays are a great thrill to the fans when they work. However, they can spell disaster if the opposing team realizes the deception and acts accordingly.

The defense also plans plays in response to expectations of what the offense will do. For example, a "blitz" (using linebackers or defensive backs to charge the quarterback) is often attempted when the team on defense expects a pass. A blitz makes downfield passing more difficult but exposes the defense to big gains if the offensive line stems the rush.

Many hours of preparation and strategizing, including film review by both players and coaches, go into the days between football games. This, along with the demanding physicality of football (see below), is why teams typically play at most one game per week.

Physicality

American football is a collision sport. To stop the offense from advancing the ball, the defense must tackle the player with the ball by knocking or pulling him down. As such, defensive players must use some form of physical contact to bring the ball-carrier to the ground, within certain rules and guidelines. Tacklers cannot kick or punch the runner. They also cannot grab the face mask of the runner's helmet or lead into a tackle with their own helmet ("spearing"). Despite these and other rules regarding unnecessary roughness, most other forms of tackling are legal. Blockers and defenders trying to evade them also have wide leeway in trying to force their opponents out of the way. Quarterbacks are regularly hit by defenders coming on full speed from outside the quarterback's field of vision. This is commonly known as a blindside.

To compensate for this, players must wear special protective equipment, such as a padded plastic helmet, shoulder pads, hip pads and knee pads. These protective pads were introduced decades ago and have improved ever since to help minimize lasting injury to players. An unintended consequence of all the safety equipment has resulted in increasing levels of violence in the game. Players may now hurl themselves at one another at high speeds without a significant chance of injury. The injuries that do result tend to be severe and often season or career-ending and sometimes fatal. In previous years with less padding, tackling more closely resembled tackles in Rugby football. Better helmets have allowed players to use their helmets as weapons. This form of tackling is particularly unwise, because of the great potential for brain or spinal injury. All this has caused the various leagues, especially the NFL, to implement a complicated series of penalties for various types of contact. Most recently, virtually any contact with the helmet of a defensive player on the quarterback, or any contact to the quarterback's head, is now a foul. During the late 1970s, the penalty in high school football for spearing included ejection from the game.

Despite protective equipment and rule changes to emphasize safety, injuries remain very common in football. It is increasingly rare, for example, for NFL quarterbacks or running backs (who take the most direct hits) to make it through an entire season without missing some time to injury. Additionally, 28 football players died from direct football injuries in the years 2000–05 and an additional 68 died indirectly from dehydration or other examples of "non-physical" dangers, according to the National Center for Catastrophic Sport Injury Research. Concussions are common, with about 41,000 suffered every year among high school players according to the Brain Injury Association of Arizona. In 1981, U.S. President Ronald Reagan, who played football in high school, commented on the contact of the sport: "Football is the last thing left in civilization where men can literally fling themselves bodily at one another in combat and not be at war."

Extra and optional equipment such as neck rolls, spider pads, rib protectors (referred to as "flak jackets"), and elbow pads help against injury as well, though they do not tend to be used by the majority of players due to their lack of requirement.

The danger of football, and the equipment required to reduce it, make regulation football impractical for casual play. Flag football and touch football are less violent variants of the game popular among recreational players.

Nutrition and dehydration

Football players typically begin their season while the weather is still extremely warm and with the dangerous combination of warm weather and high humidity, dehydration is a great risk for the players. The players are usually required to follow a hydration schedule. It is extremely important for players to drink enough fluids because dehydration can seriously reduce athletic performance and increase the risk of heat illnesses. Most trainers and coaches make it imperative for their players to drink fluids before they are thirsty.

Organization in the United States

In the United States, the major forms are high school football, college football and professional football. Most American high schools field football teams. In general, high school teams play only against other teams within the same state, but there are some exceptions like nearby schools located on opposite sides of a state line.

Most of college football in the United States is governed by the National Collegiate Athletic Association (NCAA), and most colleges and universities around the country have football teams. These teams mostly play other similarly sized schools, through the NCAA's divisional system, which divides the schools into four divisions: Division I Bowl Subdivision, Division I Championship Subdivision, Division II, and Division III. Unlike the three smaller NCAA football divisions, the Division I Bowl Subdivision does not have an organized tournament to determine its national champion. Instead, teams are invited to compete in a number of post-season bowl games. In addition, the champions of six conferences in the Division I Bowl Subdivision receive automatic bids, and four other schools receive "at-large" bids, to those five bowl games under the highly lucrative Bowl Championship Series to help determine the national champion.

The highest level major professional league in the United States is the 32-team National Football League (NFL). Another professional league, the 5-team United Football League, also currently operates. Several semi-professional, women's semi-professional football, and indoor football leagues are also played across the country.

Calendar

Traditionally, football is an autumn sport. A season typically begins in mid-to-late August and runs through December, into January. The NFL playoffs run further through January, and the Super Bowl is often played in the first week of February. As such, the sport is played in a wide range of weather conditions, from the heat and humidity of late summer, to the cold winds and snow in mid-winter. Unlike rainouts in baseball, play is only generally postponed or canceled in very extreme conditions such as lightning and hurricanes.

The NFL draft is usually held in April, in which eligible college football players are selected by NFL teams, the order of selection determined by the teams' final regular season records.

It is a long-standing tradition in the United States (though not universally observed) that high school football games are played on Friday night, college games on Saturday, and professional games on Sunday.

In the 1970s, the NFL began to schedule one game on Monday nights. Beginning in 2006, the NFL began scheduling games on Thursday and Saturday nights after the college football regular season concludes in mid-November, aired on the NFL Network.

Nationally televised Thursday-night college games have become a weekly fixture on ESPN, and most nights of the week feature at least one college game, though most games are still played on the traditional Saturday.

Certain fall and winter holidays—such as the NFL's Thanksgiving Classic and numerous New Year's Day college bowl games—have traditional football games associated with them.

Despite this, there are a few professional leagues that have played in the spring, mainly to avoid competition with the established leagues. Examples include the now defunct XFL, the United States Football League, and the proposed All American Football League. Indoor football is played primarily in spring for this same reason.

At most levels of competition, college football teams hold several weeks of practices in the spring. These practices typically end with an intramural scrimmage open to the public. In certain areas, high school football teams also hold spring practices.

Outside the United States

Outside the United States, the sport is referred to as "American football" (or a translation thereof) to differentiate it from other football codes such as association football (soccer), rugby football, Australian rules football and Gaelic football. In Australia and New Zealand the game is also known as gridiron football, or more commonly as gridiron, although in the United States the term gridiron refers only to the playing field itself. The term gridiron has also been used in the UK to describe the game. In much of the world, the term football is unambiguous and refers to association football (known commonly as 'soccer' in the United States).

Exportation by the established U.S. leagues and organizations

In 1977, the semi-pro football teams Newton Nite Hawks and Chicago Lions completed a five-game tour in Europe. These were the first professional or semi-professional American football teams to play organized games on the European continent. Games were played in Versailles, France; Lille, France; Landstuhl, Germany; Gratz Austria; and Vienna, Austria.

In 1985, Bethany College head coach and future College Football Hall of Fame member Ted Kessinger brought the first American football team to play in Sweden. The Bethany "Terrible Swedes" defeated the Swedish all-star team 72–7 in Stockholm Olympic Stadium.

The NFL has attempted to introduce the game to other nations and operated a developmental league, NFL Europa (also known as the World League of American Football and NFL Europe) with teams in various European cities, but this league was closed down following the 2007 season. The professional Canadian Football League and collegiate Canadian Interuniversity Sport play under the slightly different Canadian rules.

Major American leagues have also held some regular season games outside of the United States. On October 2, 2005, the Arizona Cardinals and San Francisco 49ers played the first regular season NFL game outside of the United States, in Mexico City's Estadio Azteca, From 2007, the NFL has played or has plans to play at least one regular season game outside of the United States during each season. The NCAA will also play games outside of the U.S. In 2012, The United States Naval Academy will play the University of Notre Dame in Dublin, Ireland.

Leagues by country

 — Gridiron Australia is the overall governing body for American football in Australia. The country is actually divided into state-level leagues instead of one national-level league by itself: ACT Gridiron (Australian Capital Territory), Gridiron NSW (New South Wales), Gridiron Queensland (Queensland), South Australian Gridiron Association (South Australia), Gridiron Victoria (Victoria), and Gridiron West (Western Australia).

 — The Belgian Football League fields 16 teams. The finalists from the playoffs determine the champion during the Belgian Bowl.

 — The Brazilian American Football League has 14 teams partitioned into north and south conferences.

 — The Vaahteraliiga or the Maple League has eight teams. The league's name comes from the name of the championship trophy Vaahteramalja ("Maple Bowl"), which was donated to the newly formed association by the embassy of Canada in Finland.

 — The German Football League has 12 teams partitioned into north and south conferences. The finalists from the playoffs determine the German champion during the German Bowl.

 — 18 registered teams participate in the MAFL's two-division league structure. The sport has grown significantly since 2004 and with some top Division I teams participating in the CEFL.

 — The Elite Football League of India (EFLI) is a proposed professional league in India. When play begins in late 2012, there will be eight teams, representing various cities across India with populations of one million or more. The ELFI will be India's first professional American football league, and its launch is backed by the Government of India and the Sports Authority of India. All of the first season's games will be held in Pune at the Shree Shiv Chhatrapati Sports Complex.

 — The Irish American Football League consists of 14 teams. Its championship game is the Shamrock Bowl.

 — Games are governed by the Israeli Football League.

 — The Italian Football League was founded in 2008, taking over previous league (National Football League Italy). It has 9 teams for the 2010 season.

 — The X-League is a professional league with 60 teams in four divisions, using promotion and relegation. After the post-season playoffs, the X-League champion is determined in the Japan X Bowl. There are also over 200 universities fielding teams, with the national collegiate championship determined by the Koshien Bowl. The professional and collegiate champions then face each other in the Rice Bowl to determine the national champion.

 — The ONEFA is a college league with 26 teams in 3 conferences.

 — American Football Wellington comprises five teams located in the Wellington area.

 — A rising number of teams (11 in 2010) compete in a two division league structure (division I which determines a national champion by a postseason playoff, and division 2 where newer and smaller teams are allowed to mature). Two teams (Oslo Vikings and Eidsvoll 1814s) regularly compete in either the European Football League or the EFAF Cup. Eidsvoll was the runner-up in EFAF Cup 2006.

 — Games are governed by the Polish American Football League.

 — Teams in the Nacionalna Liga Srbije compete in the Serbian Bowl.

 — The LNFA was founded in 1995, and currently consists of 15 clubs.

 — 70 amateur teams play in the BAFA Community Leagues (BAFACL) across a number of age ranges. The senior (adult) league has three levels: the Premiership, comprising six teams; Division 1, comprising 18 teams split across three regional conferences; and Division 2, comprising 23 teams split across four regional conferences. While the lower level teams have their own championship games during BritBowl Weekend, only Premier Division teams face each other in the BritBowl which is held in Worcester's Sixways Stadium. Unlike the NFL, the BAFACL season is played through the summer (April to September), with the British university season spanning the autumn and winter.

The IFAF and the American Football World Cup

The International Federation of American Football (IFAF) is the de facto governing body for American football, with 45 member associations from North and South America, Europe, Asia and Oceania. The organization is headquartered in La Courneuve, France. Although the IFAF has relatively little standing in the U.S. compared to the NFL, NCAA, and the other established aforementioned bodies, these same organizations also give support to USA Football, the designated U.S. representative to the IFAF.

The IFAF also oversees the American Football World Cup, which is held every four years. Japan won the first two World Cups, held in 1999 and 2003. Team USA, which had not participated in the previous World Cups, won the title in 2007.

A long term goal of the IFAF is for American football to be accepted by the International Olympic Committee as an Olympic sport. The only time that the sport was played was at the 1932 Summer Olympics in Los Angeles, but as a demonstration sport.

South America (, Sudamérica or Suramérica; ; Quechua and Aymara: Urin Awya Yala; ; ; ) is a continent situated in the Western Hemisphere, mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere. The continent is also considered a subcontinent of the Americas. It is bordered on the west by the Pacific Ocean and on the north and east by the Atlantic Ocean; North America and the Caribbean Sea lie to the northwest. It includes twelve countries: Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, Uruguay, and Venezuela. The South American nations that border the Caribbean Sea—including Colombia, Venezuela, Guyana, Suriname, as well as French Guiana, which is an overseas region of France—are also known as Caribbean South America.

The word America was coined in 1507 by cartographers Martin Waldseemüller and Matthias Ringmann, after Amerigo Vespucci, who was the first European to suggest that the lands newly discovered by Europeans were not India, but a New World unknown to Europeans.

South America has an area of 17,840,000 square kilometers (6,890,000 sq mi). Its population as of 2005 has been estimated at more than 371,090,000. South America ranks fourth in area (after Asia, Africa, and North America) and fifth in population (after Asia, Africa, Europe, and North America).

Geography

South America occupies the southern portion of the landmass referred to as the Western Hemisphere. The continent is generally delimited on the northwest by the Darién watershed along the Colombia–Panama border, or (according to some sources) by the Panama Canal which transects the Isthmus of Panama. Geopolitically and geographically all of Panama – including the segment east of the Panama Canal in the isthmus – is typically included in North America alone and among the countries of Central America. Almost all of mainland South America sits on the South American Plate. South America's triangular shape gives it the shortest coastline, for its size, of any of the continents.

Traditionally South America also includes some nearby islands. Aruba, Bonaire, Curaçao, Trinidad, Tobago, and the federal dependencies of Venezuela sit on the northerly South American continental shelf and are considered part of the continent. Geopolitically, the island states and overseas territories of the Caribbean are generally grouped as a part or subregion of North America, since they are more distant on the Caribbean Plate, even though San Andreas and Providencia are politically part of Colombia and Aves Island is controlled by Venezuela. Other islands that are included with South America are the Galápagos islands that belong to Ecuador and Easter Island (in Oceania but belongs to Chile), Robinson Crusoe Island, Chiloé are also Chilean islands, while Tierra del Fuego is split between that country and Argentina. In the Atlantic Brazil owns Fernando de Noronha, Trindade and Martim Vaz, and the Saint Peter and Saint Paul Archipelago.

South America is home to the world's highest waterfall, Angel Falls in Venezuela; the largest river (by volume), the Amazon River; the longest mountain range, the Andes (whose highest mountain is Aconcagua at 6,962 m [22,841 ft]); the driest place on earth, the Atacama Desert; the largest rainforest, the Amazon Rainforest; the highest capital city, La Paz, Bolivia; the highest commercially navigable lake in the world, Lake Titicaca; and, excluding research stations in Antarctica, the world's southernmost permanently inhabited community, Puerto Toro, Chile.

South America's major mineral resources are gold, silver, copper, iron ore, tin, and petroleum. These resources found in South America have brought high income to its countries especially in times of war or of rapid economic growth by industrialized countries elsewhere. However, the concentration in producing one major export commodity often has hindered the development of diversified economies. The fluctuation in the price of commodities in the international markets has led historically to major highs and lows in the economies of South American states, often causing extreme political instability. This is leading to efforts to diversify production to drive away from staying as economies dedicated to one major export.

South America is one of the most biodiverse continents on earth. South America is home to many interesting and unique species of animals including the llama, anaconda, piranha, jaguar, vicuña, and tapir. The Amazon rainforests possess high biodiversity, containing a major proportion of the Earth's species.

By far Brazil is the largest country in South America, encompassing around half of the continent's land area and population. The remaining countries and territories are divided among three regions: The Andean States, the Guianas and the Southern Cone.

History

Pre-history

South America was joined with Africa from the late Paleozoic Era to the early Mesozoic Era, until the supercontinent Pangaea began to rift and break apart about 225 million years ago. Therefore, South America and Africa share similar fossils and rock layers.

South America is thought to have been first inhabited by humans when people were crossing the Bering Land Bridge (now the Bering Strait) at least 15,000 years ago from the territory that is present-day Russia. They migrated south through North America, and eventually reached South America through the Isthmus of Panama. Some archaeological finds do not fit this theory and have led to an alternative theory of Pre-Siberian American Aborigines.

Agriculture and animal domestication

The first evidence for the existence of agricultural practices in South America dates back to about 9000 BC, when squashes, chillies and beans began to be cultivated for food in the highlands of the Amazon Basin. Pottery evidence further suggests that manioc, which remains a staple food today, was being cultivated as early as 2000 BC.

By 2000 BC, many agrarian village communities had been settled throughout the Andes and the surrounding religious regions. Fishing became a widespread practice along the coast, helping establish fish as a primary source of food. Irrigation systems were also developed at this time, which aided in the rise of an agrarian society.

South American cultures began domesticating llamas, vicuñas, guanacos, and alpacas in the highlands of the Andes circa 3500 BC. Besides their use as sources of meat and wool, these animals were used for transportation of goods.

Pre-Columbian civilizations

The rise of plant growing and the subsequent appearance of permanent human settlements allowed for the multiple and overlapping beginnings of civilizations in South America.

The earliest known settlements, and culture in South America and America altogether, are the Valdivia on the Southwest coast of Ecuador.

One of the earliest known South American civilizations was at Norte Chico, on the central Peruvian coast. Though a pre-ceramic culture, the monumental architecture of Norte Chico is contemporaneous with the pyramids of Ancient Egypt. Norte Chico governing class established a trade network and developed agriculture then followed by Chavín by 900 BC, according to some estimates and archaeological finds. Artifacts were found at a site called Chavín de Huantar in modern Peru at an elevation of 3,177 meters. Chavín civilization spanned 900 BC to 300 BC.

In the central coast of Peru, around the beginning of the I millennium AD, Moche (100 BC – 700 AD, at the northern coast of Peru), Paracas and Nazca (400 BC – 800 AD, Peru) cultures flourished with centralized states with permanent militia improving agriculture through irrigation and new styles of ceramic art. At the Altiplano, Tiahuanaco or Tiwanaku (100 BC – 1200 AD, Bolivia) managed a large commercial network based on religion.

Around 7th century, both Tiahuanaco and Wari or Huari Empire (600 – 1200, Central and northern Peru) expanded its influence to all the Andean region, imposing the Huari urbanism and tiahuanaco religious iconography.

The Muisca were the main indigenous civilization in what is now modern Colombia. They established a confederation of many clans, or cacicazgos, that had a free trade network among themselves. They were goldsmiths and farmers.

Other important Pre-Columbian cultures include: ; the Cañaris (in south central Ecuador), Chimu Empire (1300–1470, Peruvian northern coast), Chachapoyas, and the Aymaran kingdoms (1000–1450, Bolivia and southern Peru).

Holding their capital at the great city of Cusco, the Inca civilization dominated the Andes region from 1438 to 1533. Known as Tawantin suyu, and "the land of the four regions," in Quechua, the Inca civilization was highly distinct and developed. Inca rule extended to nearly a hundred linguistic or ethnic communities, some 9 to 14 million people connected by a 25,000 kilometer road system. Cities were built with precise, unmatched stonework, constructed over many levels of mountain terrain. Terrace farming was a useful form of agriculture.

The Mapuche in Central Chile were known for defenses against European and later Chilean settlers in the first 300 years of the Columbian period.

European colonization

In 1494, Portugal and Spain, the two great maritime European powers of that time, on the expectation of new lands being discovered in the west, signed the Treaty of Tordesillas, by which they agreed, with the support of the Pope, that all the land outside Europe should be an exclusive duopoly between the two countries.

The Treaty established an imaginary line along a north-south meridian 370 leagues west of Cape Verde Islands, roughly 46° 37' W. In terms of the treaty, all land to the west of the line (known to comprise most of the South American soil) would belong to Spain, and all land to the east, to Portugal. As accurate measurements of longitude were impossible at that time, the line was not strictly enforced, resulting in a Portuguese expansion of Brazil across the meridian.

Beginning in the 1530s, the people and natural resources of South America were repeatedly exploited by foreign conquistadors, first from Spain and later from Portugal. These competing colonial nations claimed the land and resources as their own and divided it into colonies.

European infectious diseases (smallpox, influenza, measles, and typhus)—to which the native populations had no immune resistance—and systems of forced labor, such as the haciendas and mining industry's mita, decimated the native population under Spanish control. After this, African slaves, who had developed immunities to these diseases, were quickly brought in to replace them.

The Spaniards were committed to convert their native subjects to Christianity and were quick to purge any native cultural practices that hindered this end; however, most initial attempts at this were only partially successful, as native groups simply blended Catholicism with traditional idolatry and their polytheistic beliefs. Furthermore, the Spaniards brought their language to the degree they did with their religion, although the Roman Catholic Church's evangelization in Quechua, Aymara, and Guaraní actually contributed to the continuous use of these native languages albeit only in the oral form.

Eventually, the natives and the Spaniards interbred, forming a mestizo class. At the beginning, the mestizos of the Andean region were offspring of Amerindian mothers and Spanish fathers. After independence, most mestizos had native fathers and white or mestizo mothers.

Many native artworks were considered pagan idols and destroyed by Spanish explorers; this included many gold and silver sculptures and other artifacts found in South America, which were melted down before their transport to Spain or Portugal. Spaniards and Portuguese brought the western European architectural style to the continent, and helped to improve infrastructures like bridges, roads, and the sewer system of the cities they discovered, conquered or found. They also significantly increased economic and trade relations, not just between the old and new world but between the different South American regions and peoples. Finally, with the expansion of the Portuguese and Spanish languages, many cultures that were previously separated became united through that of Latin American.

Guyana was a Portuguese, Dutch, and eventually a British colony. The country was once partitioned into three parts, each being controlled by one of the colonial powers until the country was finally taken over fully by the British.

Independence

The South American possessions of the Spanish Crown won their independence at the end of 1823 in the Spanish American wars of independence. Simón Bolívar of Venezuela and José de San Martín of Argentina were the most important leaders of the independence struggles. Bolívar led a great uprising in northern South America, then led his army southward towards Lima, the capital of the Viceroyalty of Peru. Meanwhile, San Martín led an army from the Viceroyalty of the Río de la Plata across the Andes Mountains, meeting up with General Bernardo O'Higgins in Chile, and then marched northward to gain the military support of various rebels from the Viceroyalty of Peru. The two armies finally met in Guayaquil, Ecuador, where they cornered the Royal Army of the Spanish Crown and forced its surrender.

In the Portuguese colony of Brazil, Dom Pedro I (also Pedro IV of Portugal), son of the Portuguese King Dom João VI, proclaimed the country's independence in 1822 and became Brazil's first Emperor. After some quarreling with Portuguese loyal garrisons in Bahia and Pará, this was diplomatically accepted by the crown in Portugal, on conditions of a high compensation paid by Brazil.

Although Bolivar attempted to unify politically the Spanish-speaking parts of the continent into the "Gran Colombia", they rapidly became independent states without political connections between them, despite some later attempts such as the Peruvian-Bolivian Confederation.

A few countries did not gain independence until the 20th century:

Guyana, from the United Kingdom, in 1966

Suriname, from Dutch control, in 1975

French Guiana is now a region of France. The Falkland Islands, also known as Las Malvinas remain sovereign territory of the United Kingdom, though they are much closer to Argentina, with whom they currently dispute their rightful ownership. South Georgia and South Sandwich Islands also remain sovereign territory of the United Kingdom. wnhfcio3jofvicqfiojrfvhw4ifvi4wfhvi34tfviow4hfi4hfviowhbf ir2hbvui2fhwirb2v bjwe vsw2fbcj2w v swwjvnvk2 vkfjkfjkrtneb3fgve vjufbvf jvjrn jr vr3jc fni onfv jfv jvj jkfjfggbvifgb j vhbskvgrvg grvbjrtv bwrvgwrtvgwejgbvrjkg 3fverjwvgbfrswv bwr g36yjtuj urbtrfvcwefetg yj6umny nynbytb trbvgtfvwve gthbyyntyjhnjununu nunj yny bnytrn ynryn h

Recent history

The continent became a battlefield of the Cold War in the late 20th century. Some democratically elected governments of Argentina, Brazil, Chile, Uruguay and Paraguay were overthrown or displaced by military dictatorships in the 1960s and 1970s. To curtail opposition, their governments detained tens of thousands of political prisoners, many of whom were tortured and/or killed on inter-state collaboration. Economically, they began a transition to neoliberal economic policies. They placed their own actions within the U.S. Cold War doctrine of "National Security" against internal subversion. Throughout the 1980s and 1990s, Peru suffered from an internal conflict.

Argentina and Britain fought the Falklands war in 1982.

Colombia has had an ongoing, though diminished internal conflict, which started in 1964 with the creation of Marxist guerrillas (FARC-EP) and then involved several illegal armed groups of leftist leaning ideology as well as the private armies of powerful drug lords. Many of these are now defunct, and only a small portion of the ELN remains, along with the stronger, though also greatly reduced FARC. These leftist groups smuggle narcotics out of Colombia to fund their operations, while also using kidnapping, bombings, land mines and assassinations as weapons against both elected and non-elected citizens.

Revolutionary movements and right-wing military dictatorships became common after World War II, but since the 1980s a wave of democratization came through the continent, and democratic rule is widespread now. Nonetheless, allegations of corruption are still very common, and several countries have developed crises which have forced the resignation of their governments, although, in most occasions, regular civilian succession has continued this far.

International indebtedness turned into a severe problem in late 1980s, and some countries, despite having strong democracies, have not yet developed political institutions capable of handling such crises without recurring to unorthodox economical policies, as most recently illustrated by Argentina's default in the early 21st century. The last twenty years have seen an increased push towards regional integration, with the creation of uniquely South American institutions such as the Andean Community, Mercosur and Unasur. Notably, starting with the election of Hugo Chavez in Venezuela in 1998, the region experienced what has been termed a pink tide - the election of several leftist and center-left administrations to most countries of the area, except for the Guianas, Peru and Colombia.

Politics

During the first decade of the 21st century, South American governments have drifted to the political left, with socialist leaders being elected in Chile, Uruguay, Brazil, Argentina, Ecuador, Bolivia, Paraguay, Peru and Venezuela. Despite the move to the left, South America for the most part still embraces free market policies, and it is taking an active path toward greater continental integration.

Recently, an intergovernmental entity has been formed which aims to merge the two existing customs unions: Mercosur and the Andean Community, thus forming the third-largest trade bloc in the world. This new political organization known as Union of South American Nations seeks to establish free movement of people, economic development, a common defense policy and the elimination of tariffs.

Ethnic demographics

Descendants of Indigenous peoples, such as the Quechua and Aymara, or the Urarina of Amazonia make up the majority of the population in Bolivia (55%) and, per some sources, in Peru (45%). In Ecuador, Amerindians are a large minority that comprises two-fifths of the population. The white/European population is also a significant element in most other former Spanish colonies.

The demographics of Venezuela and Colombia include approximately 25% white and European descendants, while in Peru, European descendants are the third group in importance(15%). Compared to other South American countries, the people of European descent are more of a majority in Argentina, Chile, and Uruguay, and are about half of the population of Brazil.

South America is also home to one of the largest populations of Africans. This group is also significantly present in Guyana, Brazil, Colombia, Venezuela, Suriname, French Guiana, and Ecuador. Mestizos (mixed white and Amerindian) are the largest ethnic group in Paraguay, Venezuela, Colombia and Ecuador and the second group in Peru. East Indians form the largest ethnic groups in Guyana and Suriname. Brazil followed by Peru also have the biggest Japanese, Korean and Chinese communities in South America.

Brazil is the most diverse country in South America and arguably the world, with large population of Whites, Mulattos, Mestizos, a significant population of Blacks, as well as a sizeable community of Middle Easterners and East Asians.

Indigenous peoples

Indigenous people make up about half of the population of Ecuador, Peru and Bolivia. In many places indigenous people still practice a traditional lifestyle based on subsistence agriculture or as hunter-gatherers. There are still some uncontacted tribes residing in the Amazon Rainforest.

In countries such as Chile, Colombia, Venezuela, Brazil and Argentina indigenous peoples make up a minority of the population.

Economy

During the last two decades, South American countries have experienced significant economic growth, which can be seen in many of these countries with the construction of new skyscrapers like the Gran Costanera tower in Chile, and also transportations systems like the Bogota Metro. However, because of histories of high inflation in nearly all South American countries, interest rates remain high and investment remains low. Interest rates are usually twice that of the United States. For example, interest-rates are about 22% in Venezuela and 23% in Suriname. The exception is Chile, which has been implementing free market economic policies since establishing military dictatorship in 1973 and has been increasing its social spending since the return of democratic rule in the early 1990s. This has led to economic stability and interest rates in the low single digits.

South America relies heavily on the exporting of goods and natural resources. On an exchange rate basis Brazil (the seventh largest economy in the world and the largest in South America) leads the way in total amount of exports at $137.8 billion dollars followed by Chile at 58.12 billion and Argentina with 46.46 billion.

The economic gap between the rich and poor in most South American nations is considered to be larger than in most other continents. In Venezuela, Paraguay, Bolivia and many other South American countries, the richest 20% may own over 60% of the nation's wealth, while the poorest 20% may own less than 5%. This wide gap can be seen in many large South American cities where makeshift shacks and slums lie adjacent to skyscrapers and upper-class luxury apartments.

Tourism

Tourism has increasingly become a significant source of income for many South American countries. Historical relics, architectural and natural wonders, a diverse range of foods and culture, vibrant and colorful cities, and stunning landscapes attract millions of tourists every year to South America. Some of the most visited places in the region are Machu Picchu, the Amazon Rainforest, Rio de Janeiro, Salvador, Fortaleza, Maceió, Bogota, Florianópolis, Isla Margarita, Natal, Buenos Aires, São Paulo, Angel Falls, Cuzco, Lake Titicaca, Patagonia, Cartagena and the Galápagos islands.

Culture

South Americans are culturally influenced by the historic connection with Europe, especially Spain and Portugal, and the impact of mass culture from the United States of America.

South American nations have a rich variety of music. Some of the most famous genres include vallenato and cumbia from Colombia, samba and bossa nova from Brazil, and tango from Argentina and Uruguay. Also well known is the non-commercial folk genre Nueva Canción movement which was founded in Argentina and Chile and quickly spread to the rest of the Latin America. People on the Peruvian coast created the fine guitar and cajon duos or trios in the most mestizo (mixed) of South American rhythms such as the Marinera (from Lima), the Tondero (from Piura), the 19th century popular Creole Valse or Peruvian Valse, the soulful Arequipan Yaravi, and the early 20th century Paraguayan Guarania. In the late 20th century, Spanish rock emerged by young hipsters influenced by British pop and American rock. Brazil has a Portuguese-language pop rock industry as well a great variety of other music genres.

The literature of South America has attracted considerable critical and popular acclaim, especially with the Latin American Boom of the 1960s and 1970s, and the rise of authors such as Mario Vargas Llosa, Gabriel García Márquez in novels, and Pablo Neruda and Jorge Luis Borges in other genres. The Brazilian Machado de Assis, a 19th century realist writer, is widely regarded as the greatest Brazilian writer. His admirers include José Saramago, Carlos Fuentes, Susan Sontag and Harold Bloom.

Because of South America's broad ethnic mix, South American cuisine has African, American Indian, Asian, and European influences. Bahia, Brazil, is especially well-known for its West African–influenced cuisine. Argentines, Chileans, Uruguayans, Brazilians and Venezuelans regularly consume wine. Argentina, Paraguay, Uruguay, and people in southern Chile and Brazil drinkmate, an herb which is brewed. The Paraguayan version, terere, differs from other forms of mate in that it is served cold. Pisco is a liquor distilled from grapes in Peru and Chile. Peruvian cuisine mixes elements from Chinese, Japanese, Spanish, African, Andean, and Amazonic food.

Language

Spanish (193,243,411 speakers) and Portuguese (193,197,164) are the most spoken languages in South America. Spanish is the official language of most countries, along with other native languages in some countries. Portuguese is the official language of Brazil. Dutch is the official language of Suriname; English is the official language of Guyana, although there are at least twelve other languages spoken in the country such as Hindi and Arabic. English is also spoken in the Falkland Islands. French is the official language of French Guiana and the second language in Amapa (Brazil).

Indigenous languages of South America include Quechua in Ecuador, Peru, Chile, Argentina, and Bolivia; Guaraní in Paraguay and, to a much lesser extent, in Bolivia; Aymara in Bolivia, Peru, and less often in Chile; and Mapudungun is spoken in certain pockets of southern Chile and, more rarely, Argentina. At least three South American indigenous languages (Quechua, Aymara, and Guarani) are recognized along with Spanish as national languages.

Other languages found in South America include, Hindi and Javanese in Suriname; Italian in Argentina, Brazil, Colombia, Uruguay, Venezuela, Peru and Chile; and German in certain pockets of Argentina, Brazil, Colombia, Chile, Venezuela, Peru and Paraguay. German is also spoken in many regions of the southern states of Brazil, Riograndenser Hunsrückisch being the most widely spoken German dialect in the country; among other Germanic dialects, a Brazilian form of Pomeranian is also well represented and is experiencing a revival. Welsh remains spoken and written in the historic towns of Trelew and Rawson in the Argentine Patagonia. There are also small clusters of Japanese-speakers in Brazil, Colombia and Peru. Arabic speakers, often of Lebanese, Syrian, or Palestinian descent, can be found in Arab communities in Colombia, Brazil, Venezuela, Peru, Chile, Argentina, and less frequently in Paraguay.

In most of the continent's countries, the upper classes and well-educated people regularly study English, French, German, or Italian, and are typically well-traveled. In those areas where tourism is a significant industry, English and some other European languages are often spoken. There are small Portuguese speaking areas in northernmost Uruguay because of the proximity of Brazil, as well a small Spanish speaking minority in the other side in southernmost Brazil.
