History of the National Football League on television
NBC was the first major television network to cover an NFL game, when on October 22, 1939, it broadcast a game between the Philadelphia Eagles and the Brooklyn Dodgers; the network was still only in its infancy, with only two affiliates, the modern day WRGB (now a CBS affiliate) in Schenectady and W2XBS in New York City. Portions of that game still survive via films, but the film is not footage from the telecast (recordings of television broadcasts did not begin until 1948). The use of a sideline camera, the sole camera used in the 1939 broadcast, would become the standard for all future NFL broadcasts until 2017; the angle is particularly suited for estimating yardage, compared to more mobile camera angles that began to appear in the 21st century.
NFL on NBC
On January 17, 1971, NBC's telecast of Super Bowl V between the Baltimore Colts and Dallas Cowboys was viewed in an estimated 23,980,000 homes, the largest household audience ever for a one-day sports event. The game was called by play-by-play announcer Gowdy and color commentator Rote. Although the Orange Bowl was sold out for the event, unconditional blackout rules in the NFL prohibited the live telecast from being shown in the Miami area on WSVN. The blackout was challenged in Miami-Dade District Court by attorney Ellis Rubin, and although the judge denied Rubin's request since he felt he did not have the power to overrule the NFL, he agreed with Rubin's argument that the blackout rule was unnecessary for the Super Bowl.
