Each Olympic Games has its own Olympic emblem, which is a design integrating the Olympic rings with one or more distinctive elements. They are created and proposed by the Organising Committee of the Olympic Games (OCOG) or the National Olympic Committee (NOC) of the host country. It is the responsibility of the International Olympic Committee (IOC) to approve Olympic emblems for the Olympic games. The Olympic emblems are used in promotional materials, by sponsors of the Olympics, on the uniforms of every Olympic competitor. All emblems are the property of the IOC.
