The National Football League (NFL) is the largest and most prestigious professional American football league. It is an unincorporated association controlled by its members.[1] It was formed by eleven teams in 1920 as the American Professional Football Association and adopted the name National Football League in 1922. The league currently consists of thirty-two teams from American cities and regions, divided evenly into two conferences — the AFC and NFC — of four four-team divisions.
The regular season is a seventeen-week schedule during which each team has one bye week and plays sixteen games. This schedule includes six games against a team's divisional rivals, as well as several inter-division and inter-conference games. The season currently starts on the Thursday night in the first full week of September and runs weekly to late December.
At the end of each regular season, six teams from each conference play in the NFL playoffs, a twelve-team single-elimination tournament that culminates with the NFL championship, the Super Bowl. This game is held at a pre-selected site which is usually a city that hosts an NFL team. The following week, selected all-star players from both the AFC and NFC meet in the Pro Bowl, currently held in Honolulu, Hawaii.
The NFL is arguably the most popular sports league in the United States, and has the highest per-game attendance of any domestic professional sports league in the world, drawing over 67,000 spectators per game for its most recently completed season in 2006.[2] However, the NFL's overall attendance is only approximately 20% of that of Major League Baseball, due to MLB's much longer schedule, currently 162 games per team with 81 home games each, plus playoffs.
The American Professional Football Association was founded in 1920 at a Hupmobile dealership in Canton, Ohio. The eleven founding teams initially struck an agreement over player poaching and the declaration of an end-of-season champion. Legendary athlete Jim Thorpe of the Canton Bulldogs was elected president. Only four of the founding teams finished the 1920 schedule and the undefeated Akron Pros claimed the first championship. Membership of the league increased to 22 teams in 1921, but throughout the 1920s the membership was unstable and the league was not a major national sport.
Two charter members, the Chicago Cardinals (now the Arizona Cardinals) and the Decatur Staleys (now the Chicago Bears), are still in existence. The Green Bay Packers did not begin league play until 1921: they joined the league in the summer of 1920, but failed to actually put a team on the field in the fall.
By 1934 all of the small-town teams, with the exception of the Green Bay Packers, had moved to or been replaced by teams in big cities. An annual championship game was instituted in 1933, and the annual draft of college players was first held in 1936. It was during this era, however, that the NFL became segregated: no African Americans played pro football between 1933 and 1945. One prominent franchise, George Preston Marshall's Washington Redskins, remained all-white until forced to integrate by the Kennedy administration in 1962.[4] See also Black players in American professional football
College football was the bigger attraction, but by the end of World War II, pro football began to rival the college game for fan' attention. Rule changes and innovations such as the T formation led to a faster-paced, higher-scoring game. The league also expanded out of its eastern and midwestern cradle; in 1945, the Cleveland Rams moved to Los Angeles, becoming the first big-league sports franchise on the West Coast (not counting the various teams in ice hockey's PCHA, which was a rival to the NHL in the 1910s and 1920s). In 1950, the NFL accepted three teams from the defunct All-America Football Conference, expanding to thirteen clubs. In the 1950s, with the league broadcast on national television, pro football finally earned its place as a major sport
