The WWE, an acronym for World Wrestling Entertainment, is the United States' highest level of professional wrestling. WWE matches are not considered as legitimate as other sporting events, but rather a source of entertainment and showmanship.
Vince McMahon is the CEO of WWE and is the organization's most visible authority figure. The organization's headquarters is located in Stamford, Connecticut. However, WWE has a worldwide presence and has offices in London, Tokyo and Mexico City.
WWE became a popular entity in the 1980s, when it was known as the World Wrestling Federation, or WWF. Figures such as Hulk Hogan and Roddy "Rowdy" Piper gained national prominence after participating in the early days of the WWF. The 1990s saw the arrival of other famous wrestlers, including The Undertaker and "Stone Cold" Steve Austin. The organization adopted the WWE name in 2002. The 2000s saw the arrival of new wrestlers such as Brock Lesnar and Dwayne "The Rock" Johnson.
As of August 23, 2015, Seth Rollins was the WWE heavyweight champion. Other wrestlers that were active in 2015 include John Cena, Daniel Bryan and Dolph Ziggler. WWE's primary events in 2015 are WrestleMania and Raw, where several wrestling matches occur in one night. WWE also owns NXT, a developmental division that new wrestlers enter before joining the primary WWE events.
