National Basketball Association

The National Basketball Association (NBA) is a men's professional basketball league. It is composed of 30 teams (29 in the United States and 1 in Canada) and is one of the four major professional sports leagues in the United States and Canada. It is widely considered to be the premier men's professional basketball league in the world.

The NBA was formed in 1949 after the merger of the Basketball Association of America (BAA) and National Basketball League (NBL). Although the NBA does not include the NBL's history as part of its own, this site does.

The NBA merged with the American Basketball Association in 1976, resulting in the addition of four franchises.

Teams

The NBA originated in 1946 with 11 teams, and through a sequence of team expansions, reductions, and relocations, currently consists of 30 teams. The United States is home to 29 teams; another is in Canada.

The current league organization divides 30 teams into two conferences of three divisions with five teams each. The current divisional alignment was introduced in the 2004-05 season. Reflecting the population distribution of the United States and Canada as a whole, most teams are in the eastern half of the country: 13 teams are in the Eastern Time Zone, nine in the Central, three in the Mountain, and five in the Pacific.
