NFL

The National Football League (NFL) is the premier professional American football league in the United States. It consists of 32 teams, divided into two conferences: the American Football Conference (AFC) and the National Football Conference (NFC). The NFL traces its roots to 1920, when it was founded as the American Professional Football Association; it was renamed the NFL in 1922. The AFL–NFL merger, completed in 1970, created the modern league with its current two-conference structure and divisional alignments.

Season and competition. Each team plays 17 regular-season games over 18 weeks, with one bye week. The postseason expands to 14 teams, seven from each conference, with the top seed in each conference earning a first-round bye. The playoffs culminate in the Super Bowl, a championship game played at a neutral site to determine the league champion.

Governance and economics. The league is governed by a commissioner and a board of governors representing the 32 teams. Roger Goodell has served as commissioner since 2006. The NFL operates under a collectively bargained agreement with the NFL Players Association, including a salary cap. Revenue comes from national television contracts, sponsorships, licensing, and stadium-related income.

The NFL maintains a broad cultural footprint, including an annual draft, a scouting combine, and the Pro Football Hall of Fame. It also hosts international games and supports a global media presence, contributing to its status as one of the most widely followed professional sports leagues.
