The Olympic Movement's mission is to ensure the continuation of the Olympic Games and continued success through a range of programs. The International Olympic Committee is the supreme authority of the Olympic Movement, and it is responsible for its continued development.
With the IOC acting at the top to govern the Olympic Movement, organizations also included in governing the Olympic Movement are National Olympic Committees, International Sports Federations, the Organizing Committees for the Olympic Games and athletes, officials and recognized institutions.
With the IOC holding supreme control over the Olympic Movement, the organization's main responsibilities include selecting host countries for the Olympic Games and electing new members. Beneath the IOC, as of 2012, there were 204 NOCs, which includes 53 in Africa, 41 in America, 44 in Asia, 49 in Europe and 17 in Oceania.
ISFs govern each specific sport, and they include organizations such as the International Cycling Union, the International Ski Federation, the International Ice Hockey Federation and the International Triathlon Union.
OCOGs are responsible for organizing the actual Olympic Games, which are large undertakings and take seven years to put together from the time the host city is announced through the time the Olympic Games are completed.
