The National Basketball Association, more popularly known as simply the NBA, is the world`s premier men`s professional basketball league and one of the major professional sports leagues of North America.
The NBA 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 the fall of 1949 after adding several teams from the rival National Basketball League. The league`s several international and individual team offices are directed out its head offices located in the Olympic Tower at 645 Fifth Avenue. NBA Entertainment and NBA TV studios are directed out of offices located in Secaucus, New Jersey.
The National Basketball League was a professional basketball league in the United States from 1937 to 1949. The NBL started with 13 previously independent teams in 1937–38. The league was created by three corporations General Electric, Firestone and Goodyear. The league was made up mostly by teams in small Great Lakes towns and corporate teams. The NBL lasted 12 years before merging with the three-year-old Basketball Association of America in 1949 which was renamed the National Basketball Association.
Five current NBA teams can trace their history back to the NBL. The Los Angeles Lakers, then the Minneapolis Lakers; the Sacramento Kings, then the Rochester Royals; and the Detroit Pistons, then the Ft. Wayne Pistons, joined the NBA in 1948. The Atlanta Hawks, then the Tri-Cities Blackhawks; and the Philadelphia 76ers, then the Syracuse Nationals ("Nats"), joined the NBA in 1949.
Also still surviving are the Akron Goodyear Wingfoots, the initial NBL Champion in 1938. The Wingfoots suspended operations for WWII and were not included in the NBL/BAA merger. Instead they remained in the National Industrial Basketball League (NIBL), which in 1961 became the National AAU Basketball League (NABL). The Wingfoots are still an AAU Elite team in the NABL.
