 A men's basketball tournament was first held at the 1904 Olympics as a demonstration; it has been held at every Summer Olympics since 1936.
 In the 1972 Olympics, the final game between the United States and the Soviet Union was a controversial one, as the game was ended and replayed twice by a FIBA (International Basketball Federation) official without the authority to do so, before the Soviet Union won their first gold medal, which would have been won by the United States if the game was not started against the rules.
 The U.S. filed a formal protest but was rejected by FIBA.
 As a result, the United States refused to accept the silver medal, and no player has ever claimed his medal.
 After a protest of the Soviet war in Afghanistan, the United States boycotted the 1980 Moscow Olympics.
 The Soviet Union responded by leading the 1984 Summer Olympics boycott, citing security concerns in the United States.
 Both boycotts affected basketball at the Olympics, as both had successful basketball teams at the time.
 In 1989, the International Olympic Committee (IOC) decided to allow professional athletes to compete in the Olympics, and starting in 1992, the National Basketball Association (NBA) allowed its players to participate.

Originally having participated in Olympics as the delegation of the Republic of China (ROC) from 1932 to 1948, China competed at the Olympic Games under the name of the People's Republic of China (PRC) for the first time in 1952, at the Summer Games in Helsinki, Finland, although they only arrived in time to participate in one event.
 That year, the International Olympic Committee (IOC) allowed both the PRC and the Republic of China (which recently relocated to Taiwan after the Chinese Civil War) to compete, although the latter withdrew in protest.
 Due to the dispute over the political status of China, the PRC did not participate in the Olympics again until the 1980 Winter Olympics in Lake Placid, United States.
 Their first appearance at the Summer Olympic Games after 1952 was the 1984 Summer Olympics in Los Angeles, United States.
