WWE Superstars, or simply Superstars, is an American professional wrestling television program that was produced by WWE that originally aired on WGN America in the United States and later broadcast on the WWE Network. It debuted on April 16, 2009 and ended its domestic broadcasting on April 7, 2011 . After the final domestic television broadcast, the show moved to an Internet broadcast format while maintaining a traditional television broadcast in international markets. The show featured mid-to-low card WWE Superstars in a format similar to the former shows Heat and Velocity which served the same purpose. "Enhancement talent" bouts also happened often. Big names such as John Cena, Randy Orton, The Undertaker, and Triple H appeared on the show at its beginning.
