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.
History of the National Football League on television
In 1986, the United States Football League, at the time pursuing an antitrust lawsuit against the NFL, signed an agreement with ESPN to carry games on Sunday nights. When the lawsuit failed and the 1986 season was canceled, the NFL swooped in and took the time slot, creating "ESPN Sunday Night Football" in 1987. ESPN thus became the first cable network to broadcast regular season NFL games. Chris Berman helped redefine the pre- and post-game shows when he launched "NFL Countdown" and "NFL Prime Time", and they have since become the top-rated pre- and post-game shows on television. The cable network's contract to show "ESPN Sunday Night Football" was one of the turning points in their growth, transforming them from a small cable network to a marketing empire.
