The 2012 Summer Olympics kicked off on Friday, July 27. Held in London, the games marked the third time the UK hosted the modern Olympics, making it the first country to achieve this feat. The opening ceremony, referred to as "The Isles of Wonder," featured Queen Elizabeth II, Prince Philip, Duke of Edinburgh, and performances from stars like Paul McCartney. Over 10,000 athletes from 204 National Olympic Committees competed in this year's Olympics, which involved 26 sports and 39 disciplines (including women's boxing for the first time in history). The festivities came to a close on August 12th, with the passing of the Olympic flag from London Mayor Boris Johnson to Eduardo Paes, Mayor of Rio de Janerio, whose city will host the 2016 Summer Olympics.
