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.
2007 New England Patriots–New York Giants game
"at Giants Stadium, East Rutherford, New Jersey"
In their final regular season game, the 15–0 Patriots traveled to Giants Stadium, trying to win a record 16th game of the season. With the game scheduled to air on NFL Network, not available on some cable providers, the NFL arranged a three-way simulcast of the game with CBS and NBC, the first time an NFL game was broadcast on three networks, and the first national simulcast of any NFL game since Super Bowl I. The New York and Boston television markets both had a fourth channel, a local TV station in each respective market covering the game. In the week leading up to the game, the NFL Network aired a record 65.5 hours of game-specific coverage, including a six-hour pregame special which matched the longest NFL pregame show, including for a Super Bowl, on a single network.
