Article: World Wrestling Entertainment is the largest professional wrestling organization in North America. It was called World Wrestling Federation until it changed its name because of a legal dispute. Its more than one hundred wrestlers fight each other in competitive matches that are written and practiced before they are performed. Professional wrestlers are athletes but act as entertainers. They are not seeking athletic records, but instead want to excite an audience. To do this, they use unusual names and wear special clothing during wrestling matches. These wrestlers include the Stone Cold Stunner and the Undertaker. Most professional wrestling matches are between two men or two women. They fight inside an area called a ring that is separated from the audience by ropes. Each match continues until one wrestler forces the other's shoulders to the floor and holds them there for a count of three. Most World Wrestling Entertainment matches continue for only about four to seven minutes. An organization official called a promoter decides before the match who will win. But who wins and who loses is not the important thing in professional wrestling. The important thing is that the audience enjoys the pretend fight. Some wrestlers rarely win, but continue to be popular. Not all wrestling matches are between two people. Some are called tag team matches and involve teams of two, three or four wrestlers. Another kind of match is called a battle royal. It involves thirty to sixty wrestlers competing against each other. A wrestler loses when he or she is thrown out of the ring. The winner is the last wrestler still standing.
