Roughly 100 million people will tune in to the 68-team March Madness college basketball tournament this year. Played across three weeks, in 14 cities, from the first play-in games in Dayton, OH, to the Final Four in Minneapolis, fans, cities, colleges, and broadcast partners all benefit from the plentiful madness.
The first NCAA basketball tournament tipped off 80 years ago, in 1939, and Oregon came out on top of the eight-team event, beating Ohio State in the final game, 46-33. In 1951, the field doubled to 16, and in 1975 doubled again to 32 teams. It was not until 1985 that 64 teams made the dance. The current 68-team format was adopted in 2011.
