Stargate SG-1 (often abbreviated as SG-1) is a Canadian-American adventure and military science fiction 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 feature film Stargate byDean Devlin and Roland Emmerich. The television series was filmed in and around the city of Vancouver, Canada. The series premiered onShowtime on July 27, 1997; the final episode first aired on Sky1 on March 13, 2007. With 214 episodes over 10 seasons, Stargate SG-1 had surpassed The X-Files as the longest-running North American science fiction television series, a record later broken by Smallville.
The story of Stargate SG-1 begins about a year after the events of the feature film, when the United States government learns that an ancient alien device called the Stargate can access a network of such devices on a multitude of planets. SG-1 is an elite Air Force special operationsteam, one of more than two dozen teams from Earth who explore the galaxy and defend against alien threats such as the Goa’uld, Replicators, and the Ori. The series draws upon Egyptian mythology, Norse mythology, and Arthurian legend.
The series was a ratings success for its first-run broadcasters and in syndication, and was particularly popular in Europe and Australia. Stargate SG-1 was honored with numerous awards and award nominations in its ten-season run. It also spawned the animated television series Stargate Infinity, the live-action spin-off TV series Stargate Atlantis and Stargate Universe, and the direct-to-DVD films Stargate: The Ark of Truth andStargate: Continuum. Merchandise for Stargate SG-1 includes games and toys, print media, and an original audio series.
Stargate SG-1 resumes the plot of the original feature film and follows the present-day adventures of SG-1, a military team from Earth. SG-1 and two dozen other SG teams venture to distant planets using a fictional alien portal known as a Stargate, which in the series is housed in a top-secret United States Air Force military base known as Stargate Command (SGC) underneath Cheyenne Mountain in Colorado Springs, Colorado. In the first eight seasons, the mission of the SG teams is to explore the galaxy and search for alien technology and allies to defend Earth against the Goa’uld, a snake-like parasitic alien race that takes humans as unwilling hosts. As explained in the series’ backstory, the Goa’uld transported human slaves from Earth to other habitable planets across the galaxy thousands of years ago and now pose as gods of Ancient Earth mythologies, particularly Egyptian mythology. SG-1 eventually learns that highly evolved human-like beings, known as the Ancients, had originally built the Stargate network millions of years earlier, before they used their extraordinary powers to ascend to a higher plane of existence, after which they pledged to not interfere in the lives of other species. The Ori, who belong to the same race of ascended beings as the Ancients but who use their powers to subjugate other species, forcing them to worship the Ori and to believe a doctrine of religious fundamentalism, assume the role of the main antagonists in seasons 9 and 10.
