In honor of the Olympics, I did a little research into who came up with the original logo.
Turns out it was one Baron Pierre de Coubertin, one of the head founders of the modern Olympics games. He was a French aristocrat, educator and historian. The rings were first used in June of 1914.
Coubertin stated that the ring colors stood for the colors that were on all the national flags of the countries that competed in the Olympic games (Sweden, Greece, France, England and America, Germany, Belgium, Italy, Hungary, Spain, Brazil, Australia, Japan and China) in an effort to make it an international symbol.
There was a great short article in a recent New Yorker about Sochi logo – read more.
