Olympic history was made on Wednesday when the U.S. men's swimming team won the gold medal in the 4x200 freestyle relay.
It was the 19th total medal for Michael Phelps in his Olympic career, putting him one spot above gymnast Larisa Latynina on the all-time list. Phelps also extended his record by winning his 15th gold medal.
Only a select number of athletes in the Games' history have come close to achieving the same kind of success. Just 30 athletes have won at least 10 medals in the Olympics, with Phelps being the only one to achieve double-digit gold medals.
While Phelps has dominated this decade, the 50's, 60's and 70's saw athletes from countries other than the USA be almost as good.
Here is a list of the Olympians with the most career medals in the history of the Games:
