Stargate SG-1 (often abbreviated as SG-1) is a Canadian-American 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 by Dean Devlin and Roland Emmerich. The television series was filmed in and around the city of Vancouver, British Columbia. Showtime broadcast the first five seasons beginning in 1997 before the series moved to the Sci Fi Channel for its last five seasons. The final episode premiered on Sky1 in the United Kingdom on March 13, 2007, three months before its United States premiere. With 10 seasons and 214 episodes Stargate SG-1 surpassed The X-Files in 2007 as the longest-running North American science fiction series on television, although Stargate SG-1 itself is expected to be surpassed in this record by Smallville in April 2011, as that series finishes its long run.
The story of Stargate SG-1 begins two years after the events of the feature film. A network of ancient alien devices called Stargates connects a vast multitude of planets within our Milky Way galaxy for interstellar travel. Later episodes reveal that this network is capable of spanning not just planets within the Milky Way, but with sufficient power, can provide intergalactic travel as well. Stargate SG-1 chronicles the adventures of SG-1, the flagship team of over two dozen teams from Earth who explore the galaxy and defend Earth against alien threats such as the Goa'uld, Replicators and later the Ori. The composition of the SG-1 team is stable in the show's first five seasons but changes several times in the remaining seasons. The series expands upon many Ancient Earth mythologies such as Egyptian mythology, Norse mythology, and Arthurian legend. The 2008 direct-to-DVD films Stargate: The Ark of Truth and Stargate: Continuum continue the adventures of SG-1; the third direct-to-DVD film, titled Stargate: Revolution, was confirmed in April 2009, but has been put on hold.
The series was a ratings success for Showtime and the Sci Fi Channel, and was particularly popular in Europe and Australia. Although it received little critical response, 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 in 2002, the live-action spin-off TV series Stargate Atlantis in 2004, and the live-action TV series Stargate Universe in 2009. 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 but now impassive 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. The fictional Ori, who belong to the same race as the Ancients but preach religious fundamentalism, assume the role of the main antagonists in seasons 9 and 10.
