How often is the FIBA Basketball World Cup held since 1950?

The FIBA Basketball World Cup, known as the FIBA World Championship from 1950 through 2010, is a world basketball tournament for men's national teams held once every four years by the International Basketball Federation (FIBA).

The FIBA Basketball World Cup was conceived at a meeting of the FIBA World Congress at the 1948 Summer Olympics in London. Long-time FIBA Secretary-General Renato William Jones urged FIBA to adopt a World Championship, similar to the FIFA World Cup, to be held in every four years between Olympiads. The FIBA Congress, seeing how successful the 23-team Olympic tournament was that year, agreed to the proposal, beginning with a tournament in 1950. Argentina was selected as host, largely because it was the only country willing to take on the task. Argentina took advantage of the host selection, winning all their games en route to becoming the first FIBA World Champion.

Since 1967, the champion of each tournament has been awarded the Naismith Trophy, named in honor of basketball's inventor, James Naismith (November 6, 1861 – November 28, 1939).
