NCAA Men's Division I Basketball Championship - Wikipedia, the free encyclopedia: "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 U.S., and the national semifinals (the Final Four) have become one of the nation's most prominent sports events."
