World Wrestling Entertainment, Inc. d/b/a WWE is an American professional wrestling promotion. A global integrated media and entertainment company, WWE has also branched out into other fields, including film, American football, and various other business ventures. The company is additionally involved in licensing its intellectual property to companies to produce video games and action figures.

The promotion was founded in 1953 as the Capitol Wrestling Corporation (CWC) as a Northeastern territory of the National Wrestling Alliance (NWA). Following a dispute, CWC left the NWA and became the World Wide Wrestling Federation (WWWF) in April 1963. After rejoining the NWA in 1973, the WWWF was renamed to World Wrestling Federation (WWF) in 1979 before the promotion left the NWA for good in 1983. The company's majority owner is its executive chairman, third-generation wrestling promoter Vince McMahon, who retains a 38.6% ownership of the company's outstanding stock and 81.1% of the voting power. The current entity, which was originally named Titan Sports, Inc., was incorporated on February 21, 1980, in South Yarmouth, Massachusetts, but reincorporated under Delaware General Corporation Law in 1987. It acquired Capitol Wrestling Corporation Ltd., the holding company for the WWF, in 1982. Titan was renamed World Wrestling Federation Entertainment, Inc. in 1999, and then World Wrestling Entertainment, Inc. in 2002. Since 2011, the company has branded itself solely with the initials WWE, though the legal name has not changed since 2002.WWE is the largest wrestling promotion in the world, with its main roster divided up into two primary touring groups, Raw and SmackDown, along with a developmental roster, NXT, based in Orlando, Florida (referred to by WWE as "brands"). Overall, WWE is available in more than one billion homes worldwide in 30 languages. The company's global headquarters is located in Stamford, Connecticut, with offices in New York, Los Angeles, Mexico City, Mumbai, Shanghai, Singapore, Dubai, and Munich.As in other professional wrestling promotions, WWE shows are not legitimate contests but entertainment-based performance theater, featuring story line-driven, scripted, and partially choreographed matches; however, matches often include moves that can put performers at risk of injury, even death, if not performed correctly. The pre-determined aspect of professional wrestling was publicly acknowledged by WWE's owner Vince McMahon in 1989 in order to avoid taxes from athletic commissions. WWE brands its product as sports entertainment, acknowledging wrestling's roots in competitive sport and dramatic theater.

In 2023, WWE began to explore a potential sale of the company, amidst an employee misconduct scandal involving McMahon that had prompted him to step down as chairman and CEO, although he returned as executive chairman. In April 2023, WWE made a deal with Endeavor Group Holdings, under which it would merge with Zuffa, the parent company of mixed martial arts promotion Ultimate Fighting Championship (UFC) to form TKO Group Holdings, a new public company majority-owned by Endeavor, with McMahon serving as executive chairman of the new entity, and Nick Khan becoming president. The merger is expected to be completed in the second half of 2023.
