CBS' 1976 telecast of Super Bowl X between the Pittsburgh Steelers and Dallas Cowboys was viewed by an estimated 80 million people, the largest television audience in history at the time. CBS' telecast featured play-by-play announcer Pat Summerall (calling his first Super Bowl in that role) and color commentator Tom Brookshier. Towards the end of the game, Hank Stram took over for Brookshier, who had left the booth to head down to the locker room area to conduct the postgame interviews with the winning team.
