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 CBS
On January 28, 2001, CBS Sports, Core Digital and Princeton Video Image introduced state-of-the-art, three-dimensional replay technology called "EyeVision" for its coverage of Super Bowl XXXV in Tampa (at Raymond James Stadium). The game, CBS Sports' first Super Bowl broadcast since 1992, drew 131.2 million viewers for the Baltimore Ravens win over the New York Giants. As a result, Super Bowl XXXV was the most watched television program that year. Play-by-play announcer Greg Gumbel became the first African-American announcer to call a major sports championship; he was joined in the broadcast booth with Phil Simms. Both of the Ravens' Super Bowl championships to date have been on CBS; the CBS-owned station in Baltimore, WJZ-TV, had been, as an ABC affiliate, one of the strongest TV stations for ABC Monday Night Football for most of the 1980s and early 1990s, due to Baltimore's previous NFL team, the Colts' move to Indianapolis.
