Broadcasting of sports events
NBC broadcast the first televised National Football League (NFL) game when they carried the 22 October 1939 game between the Philadelphia Eagles and the Brooklyn Dodgers. The same year, the first nationwide radio broadcast of an NFL championship game was carried on the Mutual Broadcasting System. While the NFL had weak television deals that ranked behind college football and even the Canadian Football League in the 1950s, the broadcast rights of the NFL would go on to become an important property following the 1958 NFL Championship and the later establishment of the American Football League in 1960. "Monday Night Football", "NFL on Fox", and "NBC Sunday Night Football" have changed the landscape of American football broadcasts, including the scheduling of the Super Bowl, transforming it from an afternoon broadcast into a primetime spectacle. The price for the NFL's broadcast rights has increased steadily over the past several decades, in part because of bidding wars between the numerous networks and the fear of losing stature due to the loss of NFL programming; as of the most recent contract the league nets annual fees of over $6 billion, or half of the league's overall revenue, from television rights alone. Four of the five major sports television units in the United States, and the four companies that control all of the major broadcast networks, currently own some NFL rights.
WNBC
Although full commercial telecasting began on July 1, 1941 with the first paid advertisements on WNBT, there had been experimental, non-paid advertising on television as far back as 1930. NBC's earliest non-paid, television commercials may have been those seen during the first Major League Baseball game ever telecast, a game between the Dodgers and the Cincinnati Reds, on August 26, 1939 over W2XBS. In order to secure the rights to show the game on television, NBC allowed each of the Dodgers' regular radio sponsors at the time to have one commercial during the telecast, and these were done by Dodger announcer Red Barber. For Ivory Soap, he held up a bar of the product, for Mobil gas he put on a filling station attendant's cap while giving his spiel, and for Wheaties he poured a bowl of the product, added milk and bananas, and took a big spoonful.
