Stargate

Stargate is a military science fiction media franchise, initially conceived by Roland Emmerich and Dean Devlin, based on the idea of an alien Einstein-Rosen bridge device (the Stargate) that enables nearly Instantaneous travel  across the cosmos. The franchise began with the film Stargate, released on October 28, 1994, by Metro-Goldwyn-Mayer  and Carolco. In 1997, Brad Wright and Jonathan Glassner  created a television series titled Stargate SG-1  as a sequel to the film. This show was joined by Stargate Atlantis  in 2004, and a third spin-off  series, Stargate Universe , in 2009. Also consistent with the same story are a variety of books, video games and comic books, as well as the direct-to-DVD  movies Stargate: The Ark of Truth and Continuum, which concluded the first television show after 10 seasons.
