Buffalo Bills

The Buffalo Bills are a professional American football team based in the Buffalo–Niagara Falls metropolitan area that competes in the National Football League (NFL). They are members of the league's East division of the American Football Conference (AFC). The team plays their home games at Ralph Wilson Stadium in Orchard Park, New York. The Bills are the only NFL team that plays its home games in New York State (The New York Giants and New York Jets play at MetLife Stadium, located in East Rutherford, New Jersey). The Bills conduct summer training camp at St. John Fisher College in Pittsford, New York, an eastern suburb of Rochester.

The Bills began play as an original franchise of the American Football League (AFL) in 1960. The club joined the NFL as a result of the AFL–NFL merger for the 1970 season. The 1964 and 1965 Bills were the only teams representing Buffalo that won major league professional sports championships ("back-to-back" American Football League Championships). The Bills are the only team to win four consecutive conference championships and are the only NFL team to lose four consecutive Super Bowls. The team was owned by Ralph Wilson from the team's founding in 1960, until his death in 2014 at the age of 95. After his death, Wilson's estate reached an agreement to sell the team to Terry and Kim Pegula, which was approved by the other NFL team owners on October 8, 2014. The team has featured many of the league's most prominent and popular players, including QB Jack Kemp, FB Cookie Gilchrist, G Bob Kalsu, RB O. J. Simpson, DE Bruce Smith, QB Jim Kelly, RB Thurman Thomas, and WR Andre Reed. The Bills have the longest active playoff drought in any major professional sport: they have not made the playoffs since 1999 and are the only team that has not appeared in the NFL playoffs so far in the 21st century.

National Football League

The National Football League (NFL) is a professional American football league consisting of 32 teams, divided equally between the National Football Conference (NFC) and the American Football Conference (AFC). The NFL is one of the four major professional sports leagues in North America, and the highest professional level of American football in the world. The NFL's 17-week regular season runs from the week after Labor Day to the week after Christmas, with each team playing sixteen games and having one bye week. Following the conclusion of the regular season, six teams from each conference (four division winners and two wild card teams) advance to the playoffs, a single-elimination tournament culminating in the Super Bowl, played between the champions of the NFC and AFC.

The NFL was formed in 1920 as the American Professional Football Association (APFA) before renaming itself the National Football League for the 1923 season. The NFL agreed to merge with the American Football League (AFL) in 1966, and the first Super Bowl was held at the end of that season; the merger was completed in 1970. Today, the NFL has the highest average attendance (67,591) of any professional sports league in the world and is the most popular sports league in the United States. The Super Bowl is among the biggest club sporting events in the world and individual Super Bowl games account for many of the most watched television programs in American history, all occupying the Nielsen's Top 5 tally of the all-time most watched U.S. television broadcasts by 2015. The NFL's executive officer is the commissioner, who has broad authority in governing the league.

NFL Network

NFL Network (occasionally abbreviated on-air as NFLN) is an American sports-oriented cable and satellite television network that is owned by the National Football League (NFL) and is part of NFL Media, which also includes NFL.com, NFL Films, NFL Mobile, NFL Now and NFL RedZone. Dedicated to American football, the network features game telecasts from the NFL, as well as NFL-related content including analysis programs, specials and documentaries. The network is headquartered in the Los Angeles suburb of Culver City, California, and broadcasts its worldwide feed from Encompass Digital Media (formally Crawford Communications) in Atlanta, Georgia.

As of February 2015, NFL Network is available to approximately 71,867,000 households that subscribe to a cable, satellite and telco television service in the United States (totaling 61.7% of U.S. households with at least one television set).

Background

NFL Network was launched on November 4, 2003, only eight months after the owners of the league's 32 teams voted unanimously to approve its formation. The league invested $100 million to fund the network's operations. NFL Films, which produces commercials, television programs and feature films for the NFL, is a key supplier of NFL Network's programming, with more than 4,000 hours of footage available in its library. As a result, much of the network's highlights and recaps feature NFL Films' trademark style of slow motion game action, sounds of the game, and sideline conversations between players and/or team staff.

Universal quantification

In predicate logic, a universal quantification is a type of quantifier, a logical constant which is interpreted as "given any" or "for all". It expresses that a propositional function can be satisfied by every member of a domain of discourse. In other words, it is the predication of a property or relation to every member of the domain. It asserts that a predicate within the scope of a universal quantifier is true of every value of a predicate variable.

It is usually denoted by the turned A (∀) logical operator symbol, which, when used together with a predicate variable, is called a universal quantifier ("∀x", "∀(x)", or sometimes by "(x)" alone). Universal quantification is distinct from existential quantification ("there exists"), which asserts that the property or relation holds only for at least one member of the domain.

Quantification in general is covered in the article on quantification (logic). Symbols are encoded U+2200 ∀ FOR ALL (HTML ∀ · ∀ · as a mathematical symbol).
