The National Football League (NFL) is the premier professional American football league in the United States, consisting of 32 teams divided equally between the American Football Conference (AFC) and National Football Conference (NFC). Each team plays a 17-game regular season over 18 weeks from early September to early January, followed by a 14-team playoff tournament culminating in the Super Bowl championship game in February.
Origins and Early History
The NFL originated as the American Professional Football Association (APFA), founded September 17, 1920, in Canton, Ohio, by representatives from four Ohio teams. Renamed the NFL in 1922, it crowned its first champion via standings until playoffs began in 1933. Early decades featured small-town teams like the Decatur Staleys (now Chicago Bears) and Chicago Cardinals (now Arizona Cardinals), with the league contracting amid financial woes before stabilizing post-World War II.
Growth, Classic Franchises, and NFL Ties
Television propelled growth in the 1950s-1960s; the 1966 AFL-NFL merger (effective 1970) created the modern structure and Super Bowl. Franchises like Pittsburgh Steelers (6 Super Bowls), New England Patriots (6), Dallas Cowboys (5), and San Francisco 49ers (5) built dynasties. Expansion to 32 teams by 2002 included Houston Texans; revenue sharing and salary cap ensured parity.
