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.
