The NCAA Men's Division I Basketball Championship is a single elimination tournament held each spring featuring 65[1] college basketball teams in the United States. Colloquially known as March Madness (as the tournament takes place mainly during the month of March) or the Big Dance (as opposed to the now smaller and less prestigious NIT), the tournament takes place over 3 weeks at sites across the United States, and the national semifinals (the Final Four) have become one of the nation's most prominent sporting events.
Since its 1939 inception (a brainchild of Phog Allen at the University of Kansas), it has built a legacy that includes dynasty teams and dramatic underdog stories. In recent years, friendly wagering on the event has become something of a national pastime, spawning countless "office pools" that attract expert fans and novices alike. All games of the tournament are broadcast on the CBS broadcast television network in the United States, except for the Opening Round game (or "play-in game" as it has been called), which aired on TNN in 2001, and ESPN since 2002.
The tournament bracket is made up of conference tournament champions from each Division I conference, which receive automatic bids. The remaining slots are at-large berths, with teams chosen by an NCAA selection committee. The selection process and tournament seedings are based on several factors, including team rankings, win-loss records and RPI data.
Two low-seeded teams (typically teams with poor records that qualified by winning their conference tournament championships) play the "opening round" game to determine which will advance into the first round of the tournament, with the winner advancing to play the top seed in one of the four regions. The opening Round game was added in 2001 and has been played in University of Dayton Arena in Dayton, Ohio each subsequent year. The opening round is considered part of the tournament and is often referred to as a "play-in" game.
A Most Outstanding Player honor is awarded by the Associated Press at the end of each tournament.
At 11 national titles, UCLA currently holds the record for the most NCAA Men's Division I Basketball Championships. University of Kentucky is second, with 7 national titles.
