<P> The National Collegiate Athletic Association (NCAA) Men's Division I Basketball Championship, or NCAA Tournament, is a single - elimination tournament for men's college basketball teams in the United States . It determines the champion of Division I, the top level of play in the NCAA, and the media often describes the winner as the national champion of college basketball . The NCAA Tournament has been held annually since 1939, and its field grew from eight teams in the beginning to sixty - five teams by 2001; as of 2011, sixty - eight teams take part in the tournament . Teams can gain invitations by winning a conference championship or receiving an at - large bid from a 10 - person committee . The semifinals of the tournament are known as the Final Four and are held in a different city each year, along with the championship game; Indianapolis, the city where the NCAA is based, will host the Final Four every five years until 2040 . Each winning university receives a rectangular, gold - plated trophy made of wood . </P> <P> The first NCAA Tournament was organized by the National Association of Basketball Coaches . Oregon won the inaugural tournament, defeating Ohio State 46--33 in the first championship game . Before the 1941 tournament, control of the event was given to the NCAA . In the early years of the tournament, it was considered less important than the National Invitation Tournament (NIT), a New York City - based event . Teams were able to compete in both events in the same year, and three of those that did so--Utah in 1944, Kentucky in 1949, and City College of New York (CCNY) in 1950--won the NCAA Tournament . The 1949--50 CCNY team won both tournaments (defeating Bradley in both finals), and is the only college basketball team to accomplish this feat . By the mid-1950s, the NCAA Tournament became the more prestigious of the two events, and in 1971 the NCAA barred universities from playing in other tournaments, such as the NIT, if they were invited to the NCAA Tournament . </P> <P> The University of California, Los Angeles (UCLA) has been the most successful college in the NCAA Tournament, winning 11 national titles . Ten of those championships came during a 12 - year stretch from 1964 to 1975 . UCLA also holds the record for the most consecutive championships, winning seven in a row from 1967 to 1973 . Kentucky has the second-most titles, with eight . North Carolina is third with six championships, while Duke and Indiana follow with five each . Villanova is the most recent champion, having defeated Michigan in the final of the 2018 tournament . Among head coaches, John Wooden is the all - time leader with 10 championships; he coached UCLA during their period of success in the 1960s and 1970s . Duke's Mike Krzyzewski is second all - time with five titles . </P> <Table> Legend for "Championship games" table below <Tr> <Th> Indicator </Th> <Th> Meaning </Th> </Tr> <Tr> <Th> * </Th> <Td> Game was decided in an overtime period </Td> </Tr> <Tr> <Th> </Th> <Td> Game was decided in a third overtime period </Td> </Tr> <Tr> <Th> Score </Th> <Td> Each score is linked to an article about that particular championship game, when available </Td> </Tr> <Tr> <Th> Year </Th> <Td> Each year is linked to an article about that particular NCAA Tournament </Td> </Tr> </Table>
