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.
Primary NFL television stations
Prior to the 1994 season, WDAF was the primary station for the Chiefs as an NBC affiliate (they aired on KMBC when ABC had the AFL package through 1964), since NBC had the AFC package. The interconference home games aired on KCTV starting in 1973 (when the NFL allowed local telecasts of home games). After week one of the 1994 season, WDAF switched to Fox (which got the NFC package), and has aired the Chiefs' interconference home games since. The bulk of the team's games moved to KSHB through the end of the 1997 season. Since that time, they have aired on KCTV.
