The National Football League (NFL) is the highest level of professional American football in the United States, and is considered the top professional American football league globally. It was formed by eleven teams in 1920 as the American Professional Football Association, with the league changing its name to the National Football League in 1922. The league currently consists of thirty-two teams from the United States. The league is divided evenly into two conferences – the American Football Conference (AFC) and National Football Conference (NFC), and each conference has four divisions that have four teams each, for a total of 16 teams in each conference. The NFL is an unincorporated 501(c)(6) association, a federal nonprofit designation, comprising its 32 teams.

The regular season is a seventeen-week schedule during which each team plays sixteen games and has one bye week. The season currently starts on the Thursday night in the first full week of September and runs weekly to late December or early January. At the end of each regular season, six teams from each conference (at least one from each division) play in the NFL playoffs, a twelve-team single-elimination tournament that culminates with the championship game, known as the Super Bowl. This game is held at a pre-selected site which is usually a city that hosts an NFL team.

The Football League, also known as the npower Football League for sponsorship reasons, is a league competition featuring professional association football clubs from England and Wales. Founded in 1888, it is the oldest such competition in world football. It was the top level football league in England from its foundation in the 19th century until 1992, when the top 22 clubs split away to form the Premier League (reduced to 20 clubs in 1995).

The Football League has been associated with a title sponsor since 1983. As this sponsor has changed over the years the league has been known in turn as the Canon League, the Today League, the Barclays League, the Endsleigh League, the Nationwide Football League and the Coca-Cola Football League, until the present sponsor npower was adopted in 2010, contracted until 2013.

Since 1995 it has had 72 clubs evenly divided into three divisions, which are known as The Championship, League One, and League Two. Promotion and relegation between these divisions is a central feature of the League and is further extended to allow the top Championship clubs to exchange places with the lowest placed clubs in the Premier League, and the bottom clubs of League Two to switch with the top clubs of the Football Conference, thus integrating the League into the English football league system. Although primarily a competition for English clubs, one club from Wales also takes part, while in the past Swansea City, Wrexham, Newport County, Merthyr Town and Aberdare Athletic have been members.

Adrian Lewis Peterson (born March 21, 1985), nicknamed "A. D." (for "All Day"), "A. P." and "Purple Jesus", is an American football running back for the Minnesota Vikings of the National Football League (NFL). Peterson was selected by the Vikings with the seventh overall pick in the 2007 NFL Draft. He played college football at the University of Oklahoma.

While at Oklahoma, Peterson set the NCAA freshman rushing record with 1,925 yards as a true freshman during the 2004 season. As a First-team All-American, he became the first freshman to finish as the runner-up in the Heisman Trophy balloting behind USC quarterback Matt Leinart. Peterson finished his college football career as the Sooners' third all-time leading rusher.

Following his stellar first pro season in which he set an NFL record for most rushing yards in a single game (296), Peterson was named the NFL Offensive Rookie of the Year. He was then awarded the MVP award for his performance in the Pro Bowl and became only the fifth player in NFL history to have more than 3,000 yards through his first two seasons. In 2010, he became the fifth fastest player to run for 5,000 yards, doing so in his 51st game. Currently, Peterson has the fourth highest average rushing yards per game total in NFL history (min. 50 games) with an average of 92.5, trailing Jim Brown (104.3), Barry Sanders (99.8) and Terrell Davis (97.5).

Jacqueline Marie "Jackie" Evancho ( /iːˈveɪŋkoʊ/ ee-VAYNG-koh; born April 9, 2000) is an American classical crossover singer who has gained wide recognition at an early age.

Between 2008 and 2010, Evancho entered several talent competitions; made singing appearances, mostly in Pennsylvania; issued an independent album, Prelude to a Dream; and attracted interest on YouTube. Later in 2010, at the age of 10, she gained wider popularity with her performances in the fifth season of the America's Got Talent (AGT) competition, finishing in second place. With the subsequent release of her O Holy Night EP, she became the best-selling debut artist of 2010, the youngest top-10 debut artist in U.S. history and the youngest solo artist ever to go platinum. In June 2011, her first full-length major-label album, Dream With Me, debuted at #2 on American album charts, and she became the youngest top-5 debut artist in UK history. Billboard ranked Evancho the top Classical Albums Artist for 2011.

Evancho impressed composers Tim Janis and David Foster, each of whom included her in his concerts beginning in 2009. Foster later produced Evancho's album, Dream With Me, and subsequent PBS special for the television series, Great Performances. Evancho performed in front of U.S. President Barack Obama at the 2010 National Christmas Tree lighting in Washington, D.C. She is the ambassador for "Mission: Humane", a Humane Society program which encourages children's involvement in the protection of animals. She features songs from Dream With Me in a 2011–12 concert tour with symphony orchestras. Evancho released another studio album, Heavenly Christmas, in November 2011. The same month, she became the youngest person ever to give a solo concert at Lincoln Center in New York City. A national cotillion organization listed her as one of the "ten best-mannered people of 2011".
