NBC Sunday Night Football is a weekly television broadcast of National Football League (NFL) games on NBC 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 (concurrently with NBC assuming the rights to Sunday evening regular-season games, ESPN took over the broadcast rights to Monday Night Football from sister network ABC beginning with the 2006 season). Previously, NBC had aired American Football League (AFL), and later American Football Conference (AFC), games from 1960 until 1998, when CBS took over those rights.
