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.
NFL on NBC
NBC's 1989 telecast of Super Bowl XXIII between the San Francisco 49ers and Cincinnati Bengals was watched by an estimated 110,780,000 viewers, according to ACNielsen, making it the sixth most-watched program in television history. The game was Merlin Olsen's final Super Bowl broadcast, as he was demoted the following season to make room for Bill Walsh. The game featured a special segment by Frank Deford profiling recently deceased Pittsburgh Steelers owner Art Rooney. This was also the first NFL game that NBC covered with their new "Quantel Cypher" graphics system, which was introduced during their coverage of the 1988 Seoul Olympics (the network had used Chyron for their graphics prior to Super Bowl XXIII). With the win, the 49ers became the first team to win Super Bowls televised on three different networks (the other two being Super Bowl XVI on CBS and Super Bowl XIX on ABC). Since then, the Washington Redskins (in 1992), the Green Bay Packers (in 1997), the Pittsburgh Steelers (in 2006) the New York Giants (in 2008) the New England Patriots (in 2015) and the Denver Broncos (in 2016) have accomplished this same feat. This was the last outdoor Super Bowl to start earlier than 6:00 pm Eastern Time, as it started just after 5:00 pm.
