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.

One of the most remembered games on NBC was a 1968 game known as the "Heidi Game". As its nationally televised game between the Oakland Raiders and New York Jets running late, the network discontinued coverage while the game was still playing to air the movie "Heidi" just moments after the Jets' Jim Turner kicked what appeared to be the game-winning field goal with 1:05 remaining. While millions of irate fans, missing the finale, jammed NBC's phone lines, the Raiders scored two touchdowns in eight seconds during the final minute to win 43–32.
