On 17 May 1939, the United States' first televised sporting event, a college baseball game between the Columbia Lions and Princeton Tigers, was broadcast by NBC from Columbia's Baker Field. (The world's first live televised sporting event had been the 1936 Summer Olympics in Berlin.) On 30 September 1939, the first American football game, a college contest between Fordham and Waynesburg College was broadcast on television. The first nationwide broadcast of college football, which was also the first live sporting event seen coast-to-coast, was a game between Duke University and the University of Pittsburgh that was televised by NBC on 29 September 1951. The broadcasting of college football games on television in the United States has been a fixture of the major networks on a continuous basis since that time. The NCAA severely restricted broadcasts of college football from the 1950s until a judge ruled that the action was a violation of antitrust rules in 1984, which allowed for a much greater expansion of college football broadcasting.
