By 1955, NBC became the television home to the NFL Championship Game, the precursor to the Super Bowl, paying US$100,000 to the league for the rights. The network had taken over the broadcast rights from the DuMont Television Network, which had struggled to give the league a national audience (NBC's coverage of proto-Canadian Football League games from the year prior was more widely available at the time) and was on the brink of failure; the NFL's associations with NBC (as well as with CBS) proved to be a boost to the league's popularity. For the 1957 NFL Championship Game, Van Patrick and Ken Coleman split a half of the play-by-play duties and Red Grange, normally on play-by-play for Chicago Bears games on CBS, assumed the color commentator role for this game. The 1958 NFL Championship Game, played at Yankee Stadium, between the Baltimore Colts and the New York Giants went into sudden death overtime. This game, since known as the "Greatest Game Ever Played", was seen by many throughout the country and is credited with increasing the popularity of professional football in the late 1950s and early 1960s. Chris Schenkel called the first half while Chuck Thompson called the second half and overtime.
