Stargate SG-1 (stylized as STARGᐰTE SG·1 and often abbreviated SG-1) is a Canadian-American military science fiction adventure television series and part of Metro-Goldwyn-Mayer's "Stargate" franchise. The show, created by Brad Wright and Jonathan Glassner, is based on the 1994 science fiction film "Stargate" by Dean Devlin and Roland Emmerich. The television series was filmed in and around the city of Vancouver, British Columbia, Canada. The series premiered on Showtime on July 27, 1997 and moved to the Sci Fi Channel on June 7, 2002; the final episode first aired on Sky1 on March 13, 2007.
