The Summer Olympic Games
or the Games of the Olympiad
, first held in 1896, is a major international multi-sport event normally held once every four years. The most recent Summer Olympics were held in Rio de Janeiro, Brazil. The International Olympic Committee (IOC) organises the Games and oversees the host city's preparations. In each Olympic event, gold medals are awarded for first place, silver medals are awarded for second place, and bronze medals are awarded for third place; this tradition began in 1904. The Winter Olympic Games were created out of the success of the Summer Olympics.
