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 and one is located in Canada. The Boston Celtics have won the most championships with 17 NBA Finals wins. The second most successful franchise is the Los Angeles Lakers, who have 16 overall championships (11 in Los Angeles, 5 in Minneapolis). Following the Lakers are the Chicago Bulls with six championships, all of them over an 8-year span during the 1990s, and the San Antonio Spurs with four championships, all since 1999.

The current league organization divides thirty teams into two conferences of three divisions with five teams each. The current divisional alignment was introduced in the 2004–05 season.
