wrestling, before transitioning to its theatrical form. A popular performer, Kurt Angle, is the first Olympic gold medalist in professional wrestling history, having won his gold medal at the 1996 Summer Olympic Games in freestyle wrestling. Another prominent performer is Brock Lesnar, a former NCAA Wrestler who won the NCAA Division I National Championship in 2000. Dramatic elements While each wrestling match is ostensibly a competition of athletics and strategy, the goal from a business standpoint is to excite and entertain the audience. Although the competition is staged, dramatic emphasis draws out the most intense reaction. Heightened interest results in higher attendance, increased ticket sales, higher ratings on television broadcasts (greater ad revenue), higher pay-per-view buyrates, and sales of branded merchandise and recorded video footage. All of these contribute to the profit of the promotion company. Character/gimmick In Latin America and English-speaking countries, most wrestlers (and other on-stage performers) portray character roles, sometimes with personalities wildly different from their own. These personalities are a gimmick intended to heighten interest in a wrestler without regard to athletic ability. Some can be unrealistic and cartoon-like (such as Doink the Clown), while others carry more verisimilitude (such as Chris Jericho, The Rock, John Cena, Steve Austin, and CM Punk). In lucha libre, many characters wear masks, adopting a secret identity akin to a superhero or a supervillain, a near-sacred tradition. An individual wrestler may use their real name, or a minor variation of it, for much of their career, such as Bret Hart, John Cena and Randy Orton. Others can keep one ring name for their entire career (Shawn Michaels, CM Punk and Ricky Steamboat), or may change from time to time to better suit the demands of the audience or company. Sometimes a character is owned and trademarked by the company, forcing the wrestler to find a new one when he leaves (although a simple typeset change, such as changing Rhyno to Rhino, can get around this), and sometimes a character is owned by the wrestler. Sometimes, a wrestler may change their legal name to obtain ownership of their ring name (Andrew Martin and Warrior). Many wrestlers (such as The Rock and The Undertaker) are strongly identified with their character, even responding to the name in public or between friends. Proper decorum is for wrestlers to refer to each other by their stage names/characters rather than their birth/legal names, unless otherwise introduced.
