Questions related to the National Basketball Association (NBA).

The National Basketball Association (NBA) is the pre-eminent men's professional basketball league in North America. It consists of thirty franchised member clubs, of which twenty-nine are located in the United States and one (the Toronto Raptors) in Canada. It is an active member of USA Basketball (USAB), which is recognized by the International Basketball Federation, FIBA, as the national governing body for basketball in the United States.

The NBA is one of the 4 major North American professional sports leagues (the other three being the NFL for American football, MLB for baseball, and the NHL for ice-hockey). NBA players are the world's best paid sportsmen by average annual salary per player, largely owing to the massive popularity of the sport and the relatively short player rosters (only 10 players are on the roster for each NBA game, as opposed to 60 for NFL football, 20 for NHL hockey and 25 for Major League Baseball). NBA basketball is the second most popular live spectator sport in the United States after NFL football, and the third most popular televised sport after the NFL and NASCAR.

The league was founded in New York City on June 6, 1946 as the Basketball Association of America (BAA). The league adopted the name National Basketball Association in 1949 after merging with the rival National Basketball League (NBL). The league's several international as well as individual team offices are directed out of its head offices located in the Olympic Tower at 645 Fifth Avenue in New York City. NBA Entertainment and NBA TV studios are directed out of offices located in Secaucus, New Jersey.
