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.

In the end, 15.7 million viewers watched the game on CBS, 13.2 million on NBC, 4.5 million on the NFL Network, and 1.2 million on the aforementioned local stations in New York, Boston, and Manchester. The game was the most watched program on television since the 2007 Academy Awards and the most watched regular season NFL game in more than 12 years. It marked the first time that an NFL game was simulcasted on two or more networks on a national level since Super Bowl I, which aired on CBS and NBC, the respective homes of the NFL and the American Football League at the time.
