The NBA was founded in 1946 as a merger between two existing leagues, namely BAA (Basketball Association of America) and NBL (National Basketball League). The league was renamed NBA after merging with another league called ABA (American Basketball Association) in 1976. The league currently consists of 30 teams based in major cities across North America.
FIBA was founded as an international governing body for basketball in 1932 but did not start organizing championships until the 1950s. It now organizes world championships and other international competitions such as Olympics Games or World Cup Winning Team since its formation until today except during World War II.
The main difference between these two leagues is that while FIBA has been established since 1940 to oversee international competitions, it only became an official organization in 2000 after it separated from its governing body from 1998, known as FISB (Fédération Internationale de Basketball Amateur). The NBA was formed in 1946 as a professional basketball league for men's teams based in America. It has 30 teams and has been growing rapidly over time with more than half of its players being foreign born.
