The NBA began life as the Basketball Association of America in 1946 and played under that monkier for 3 years before, in 1949, merging with the National Basketball League and changing names to the NBA. The BAA started out with 11 teams in 1946 but lose four of them before the start of the next season. Despite the loss of four teams the BAA was having a lot of success against its rival the NBL and was able to entice four of the NBL’s premire franchises to join the BAA in 1948.
