The FIBA Intercontinental Cup, commonly referred to as the FIBA World Cup for Champion Clubs, or the FIBA Club World Cup, is a professional basketball competition endorsed by FIBA, FIBA Americas and Euroleague Basketball Company. Historically, its purpose has been to gather the premier basketball clubs from each of the world's geographical zones, and to officially decide the best club of the world, which is officially crowned as the world club champion. The World Cup for Clubs has been contended mainly by the champions of the continents and/or world geographical regions that are of the highest basketball levels.
Currently, the champions of the FIBA Americas League play against the champions of the Euroleague, in an aggregate score two-legged series that determines the official world club champion. The league champions of the NBA, which would be considered the top club from the North American zone, currently decline participation.
The FIBA Intercontinental Cup competition was originally organized between the years 1966 and 1987. The tournament had its origins with a friendly test game in São Paulo in 1965. The test game was contested by the South American Club Championship champions Corinthians, and the FIBA European Champions Cup champions, Real Madrid. Corinthians won the test game by a score of 118 to 109. After the success of the test tournament, the first official tournament took place in the year 1966.
In 1973, the competition adopted the name FIBA Intercontinental Cup William Jones, to honor the secretary general of FIBA, William Jones. FIBA tried to rebirth the competition in 1996, by reorganizing the Intercontinental Cup into a best-of-three playoff tournament between the winners of the Euroleague and the winners of the South American League (the champions of all of South America). After that tournament however, the competition was succeeded by the McDonald's Championship, which preexisted and included NBA clubs. The McDonald's Championship however, was not an official tournament like the Intercontinental Cup.
