Stargate SG-1 (often abbreviated as SG-1) is an American-Canadian science fiction television series, part of the Stargate franchise. Its story begins one year after the events of the 1994 science fiction film Stargate. It was produced in and around Vancouver, Canada.
In the Stargate science fiction universe, a network of ancient alien devices called Stargates connects the far reaches of several galaxies, including the Milky Way, Pegasus and Ori galaxies, opening the door for near-instantaneous interstellar travel. Stargate SG-1 chronicles the exploits of SG-1, the "flagship team" of at least 25 teams who explore the galaxy and defend Earth against alien threats such as the Goa'uld, Replicators and later the Ori.
The series is currently broadcast in several countries around the world; in some places, such as Europe, North America, Japan, Latin America and Australia, the series is broadcast in HD.
In 2007, after completion of the series run, Stargate SG-1 was named as number 28 on TV Guide's list of "The 30 Top Cult Shows Ever"

Developed for television by Jonathan Glassner and Brad Wright, Stargate SG-1 was produced by MGM and filmed at Bridge Studios in Vancouver. The first episode was broadcast on July 27, 1997 on Showtime in the US and December 3, 1997 on the Seven Network in Australia. Showtime produced and aired the show's first five seasons. Beginning with season six, it was produced and aired by the Sci Fi Channel. A spin-off series, Stargate Atlantis, began airing in 2004. The two shows ran in tandem for three years, with occasionally interconnected plots and simultaneous story timelines.
Stargate SG-1 became the longest-running North American science fiction series on television, surpassing the nine seasons and 202 episodes of the The X-Files. It is also listed in the 2007 Guinness World Records as the "longest-running science fiction show (consecutive)"; Doctor Who fans dispute this claim, as 694 episodes of the British show were produced and shown consecutively between 1963 and 1989.
On August 21, 2006, the Sci Fi Channel announced that it would not be renewing the show for an eleventh season; however, executive producer Robert C. Cooper stated that Stargate SG-1's story will continue in a yet-to-be-announced form. Metro-Goldwyn-Mayer announced that they are very keen to carry on the Stargate SG-1 story, and that they "intend to vigorously find a way to extend the franchise". Two Stargate films are currently planned, a continuation of the Stargate SG-1 story lines (see List of Stargate SG-1 episodes). The last day of shooting for season ten was on October 5, 2006. The final episode "Unending" was first broadcast by Sky One in the UK on March 13, 2007, and was later aired by the Sci Fi Channel in the United States on June 22, 2007.
In December, 2006, there were suggestions that a third Stargate series was being developed by the team behind Stargate SG-1 and Stargate Atlantis. The working title of this series is Stargate Universe.
