The Summer Olympic Games also known as the Games of the Olympiad, are a major international multi-sport event normally held once every four years. The Games were first held in 1896 in Athens, Greece, and were most recently held in 2016 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.
