Stargate

Stargate is a military science fiction media franchise owned by Amazon MGM Studios. It is based on the film directed by Roland Emmerich, which he co-wrote with producer Dean Devlin; production company StudioCanal owns the rights to the original film. The franchise is based on the idea of an alien wormhole (specifically an 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, which grossed US$197million worldwide. 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, Stargate Universe in 2009, and a prequel web series, Stargate Origins, in 2018. 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: Children of the Gods, Stargate: The Ark of Truth, and Stargate: Continuum, which concluded the first television show after 10 seasons.

In 2011, Stargate Universe, the last Stargate program on television, ended its run. Brad Wright announced that there were no more plans to continue the same story in further productions. In 2016, comic publisher American Mythology acquired the rights to publish new Stargate Atlantis stories set within the established franchise canon. This was expanded in 2017 to include new Stargate Universe comics as well, resolving the cliffhanger that ended the show. The predominant story arc thus ran for more than 15 years, including 18 seasons (364 episodes) of programming, and 22 comic book issues as of January 2020. However, a variety of other media either ignore this main continuity or reset it, while maintaining essential elements that define the franchise (mainly, the inclusion of a Stargate device). These include the 2002 animated series Stargate Infinity.
