NBC Sunday Night Football is an American weekly television broadcast of National Football League (NFL) games on NBC and Peacock in the United States. It began airing on August 6, 2006, with the Pro Football Hall of Fame Game, which opened that year's preseason. NBC took over the rights to the Sunday prime time game telecasts from ESPN, which carried the broadcasts from 1987 to 2005. At the same time, ESPN began broadcasting Monday Night Football when it was dropped from sister network ABC. Previously, NBC had aired American Football League (AFL), and later American Football Conference (AFC), games from 1965 until 1997, when CBS took over those rights.

The National Football League (NFL) is a professional American football league that consists of 32 teams, divided equally between the American Football Conference (AFC) and the National Football Conference (NFC). The NFL is one of the major professional sports leagues in the United States and Canada and the highest professional level of American football in the world. Each NFL season begins annually with a three-week preseason in August, followed by the 18-week regular season which runs from early September to early January, with each team playing 17 games and having one bye week. Following the conclusion of the regular season, seven teams from each conference advance to the playoffs, a single-elimination tournament that culminates in the Super Bowl, which is contested in February and is played between the winners of the AFC and NFC championship games.
