Date: 1936-1972
Once basketball was accepted as a medal sport in the Olympics, the Americans dominated. The US went undefeated in seven straight Olympiads, winning 63 straight until the controversial gold medal game vs. the USSR in 1972. Team USA regrouped and went on a 21-game winning streak from 1976-1988 until they lost to their arch rival, the Soviet Union. A loss that played a part in NBA players being allowed to participate in the Games.
