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.
Fútbol Americano
As of 2016, the 2005 Fútbol Americano game was one of only four NFL games played outside the US to have aired on American national television, the others being a New York Jets-Buffalo Bills game in Toronto in 2009, which aired on NFL Network; a Detroit Lions–Atlanta Falcons game in 2014 in London that started at 9:30 a.m. ET and was broadcast nationally on FOX; and an International Series game between the Houston Texans and Oakland Raiders in 2016 held at Estadio Azteca in Mexico City and televised by ESPN. The latter game was the first "Monday Night Football" game held outside the U.S.
