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.
Announcerless game
The announcerless game was an American football contest played on December 20, 1980, between the New York Jets and the Miami Dolphins of the National Football League. As an experiment, the NBC television network broadcast it without assigning any commentators to cover it. The two teams were playing the last game of that season for them as neither had qualified for the playoffs, and since the game was being broadcast nationally NBC executive Don Ohlmeyer decided on the idea to boost what would otherwise have been weak ratings. The Jets won a 24–17 upset victory.
