The Olympic Movement encompasses a large number of national and international sporting organisations and federations, recognised media partners, as well as athletes, officials, judges, and every other person and institution that agrees to abide by the rules of the Olympic Charter.[85] As the umbrella organisation of the Olympic Movement, the International Olympic Committee (IOC) is responsible for selecting the host city, overseeing the planning of the Olympic Games, updating and approving the Olympic sports programme, and negotiating sponsorship and broadcasting rights.[86]
