BASKETBALL
The National Basketball Association (NBA) is the pre-eminent men's professional basketball league in North America, and is widely considered to be the premier men's professional basketball league in the world. It has 30 franchised member clubs (29 in the United States and 1 in Canada), and is an active member of USA Basketball (USAB), which is recognized by FIBA (also known as the International Basketball Federation) as the national governing body for basketball in the United States. The NBA is one of the four major North American professional sports leagues. NBA players are the world's best paid sportsmen, by average annual salary per player.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 on August 3, 1949, after merging with its 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.
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 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. Reflecting the population distribution of the United States and Canada as a whole, most teams are in the eastern half of the country: thirteen teams are in the Eastern Time Zone, nine in the Central, three in the Mountain, and five in the Pacific.
