A professional wrestling promotion (also federation or fed) is a company or business that regularly performs shows involving professional wrestling. "Promotion" also describes a role which entails management, advertising and logistics of running a wrestling event (see promoter). Within the convention of the show, the company is a sports governing body which sanctions wrestling matches and gives authority to the championships and is responsible for determining the divisions, rankings, etc. of wrestlers. In truth, the company serves as a touring theatre troupe, as well as event promotion body for its own events.
