The letters NBA stand for the National Basketball Association, and this is the pre-eminent professional basketball league in North America. The league was established in New York City in 1946 as the Basketball Association of America, but adopted the present name three years later, after merging with the National Basketball League. The international as well as the individual team offices are directed from its head offices, which are in the Olympic Tower in New York City. Associated businesses, NBA Entertainment and NBA TV Studios are operated from offices located in New Jersey.
