Query: How long did Stargate SG-1 air for?
Stargate SG-1 premiered on July 27, 1997 on the subscription channel Showtime. After five seasons on the same network, the Sci Fi Channel bought Stargate SG-1 and would air it for five further seasons, totalling to 214 episodes in ten seasons (seasons 1 through 7 consisted of 22 episodes each, and seasons 8 through 10 had 20 episodes each). Since the American broadcast splits each season to allow the production to catch up, the British channel Sky One aired the second part of some seasons before their American counterpart. Stargate SG-1's finale episode premiered in the United Kingdom on Sky One on March 13, 2007. The Sci Fi Channel concluded the tenth season on June 22, 2007. All seasons of Stargate SG-1 are available on DVD, and two direct-to-DVD Stargate films have continued the series, the first released in March 2008, the second in July 2008.
DeLuise has made guest appearances on the television shows "The Facts of Life", "21 Jump Street" spin-off "Booker", "Friends", "Supernatural", "", "Gene Roddenberry's Andromeda", and "Stargate SG-1".
In 1997, he began working on the series "Stargate SG-1", serving as producer, writer, director, and creative consultant. He has appeared, normally as an extra, in every episode of the series he has directed. He went on to work as executive producer, director and writer for the "Stargate SG-1" spin-off "Stargate Atlantis", and directed eight episodes of the spin-off "Stargate Universe". His father, Dom DeLuise, made a guest appearance in the "Stargate SG-1" episode "Urgo", which Peter directed. Peter also made a cameo in the episode as the "Urgo" character transformed to be a young man in a United States Air Force uniform.
The fourth season of "Stargate Atlantis", an American-Canadian television series, began airing on September 28, 2007 on the US-American Sci Fi Channel. The fourth season concluded after 20 episodes on March 7, 2008 on Sci Fi. The series was developed by Brad Wright and Robert C. Cooper, who also served as executive producers. Amanda Tapping (Col. Samantha Carter) joins the cast as a regular for 14 episodes, Jewel Staite (Dr. Jennifer Keller) was a recurring character for eleven episodes, while regular cast member Torri Higginson (Dr. Elizabeth Weir) was a recurring cast member for four episodes. Other season four regular cast members include Joe Flanigan, David Hewlett, Rachel Luttrell and Jason Momoa.Episodes in bold are continuous episodes, where the story spans over 2 or more episodes.
With the season premier, "Adrift", Amanda Tapping replaces Torri Higginson in the opening credits sequence, with Paul McGillion no longer appearing. This marks Amanda Tapping's first appearance as a main character on Atlantis. It also marks the only time an actor has appeared in the opening credits of both "Stargate SG-1" and Atlantis. Christopher Judge has a cameo appearance as his "Stargate SG-1" character Teal'c in "Reunion" and guest stars in the episode "Midway". Judge is the last original "Stargate SG-1" regular to appear on Atlantis, as the other three characters in the original SG-1 team all appeared in Atlantis's first season, as did other SG-1 characters Hank Landry and George Hammond. Of the three other SG-1 regulars (namely Cam Mitchell, Vala Mal Doran and Jonas Quinn), Mitchell and Vala visited Atlantis in the SG-1 crossover episode "The Pegasus Project". Jodelle Ferland, who plays Princess Harmony in the episode "Harmony", previously appeared in the episode "Flesh and Blood" in Stargate SG-1 season 10 as a young Adria; and Crystal Lowe previously appeared in the episode "Emancipation" in season 1 of Stargate SG-1, in the two-part "The Kindred" Luke Perry and Rebecca Gayheart reprised the roles from 1997 miniseries "Invasion" as both Beau Stark (in Carter's Dream) and Cassie Winslow and Christopher Orr and Connor Trinneer both reprising as Pitt Henderson and Michael Kenmore respectively.
Doctor Rodney McKay is a contractor for the United States Air Force and makes his first appearance in the "Stargate SG-1" episode "48 Hours", the fourteenth episode of "Stargate SG-1" Season 5, as a scientist who joins the fictional Stargate Program. McKay was seen in two more episodes of "Stargate SG-1" before becoming a main character in "Stargate Atlantis" which was set in the Pegasus Galaxy. His next appearances in "Stargate SG-1" were in Alternate timeline and different realities until the crossover episode "The Pegasus Project" in season ten. Overall, McKay and Joe Flanigan's character John Sheppard are the only two characters who appeared in every episode of "Stargate Atlantis", with McKay being the character with the most screentime.
The first season of "Stargate Atlantis" was filmed in parallel to the eighth season of "SG-1", and aired in the time slot immediately following "SG-1". Richard Dean Anderson and Michael Shanks appeared in the pilot episode of "Stargate Atlantis". Beginning with "New Order" and continuing into the spinoff series "Stargate Atlantis", Torri Higginson replaced Jessica Steen as Dr. Elizabeth Weir. Ellie Harvie, who first appeared in "Prometheus Unbound" as Lindsey Novak, later became a recurring character on "Stargate Atlantis"

The core of the fictional Stargate Program is Stargate Command (SGC), a publicly undisclosed military unit organized under the Department of the Air Force, and based at the Cheyenne Mountain Air Force Station near Colorado Springs, Colorado. (and at Creek Mountain Facility, a fictional name for Cheyenne Mountain in the "Stargate" film). Although on-base support personnel wear patches of Air Force Space Command (AFSPC), it has not been clarified whether or not Stargate Command itself is a component of that organization or a separate entity. Stargate Command, also referred to by its codename "Area 52", is tasked with operating the Stargate on Earth and coordinates exploration and diplomatic relationships through the Stargate. Long-term research of alien technology is usually moved from the SGC to Area 51 in Nevada. Stargate Command is constituted and activated in the pilot episode of "Stargate SG-1", "Children of the Gods", when the Goa'uld threat is first recognized. The writers considered replacing "Stargate SG-1" with a new show named "Stargate Command" after "SG-1"'s eighth season, but the Sci Fi Channel decided to continue "SG-1" for two more seasons instead.
The episode "Ripple Effect" was overly long and had many scenes edited and cut for time. Writer Joseph Mallozzi later posted script sections of all cut scenes online. Asked what the cryptic remark by Black Mitchell meant when he left through the gate at the end of the episode, Mallozzi answered the meaning of this remark will not be revealed in the series but might come up in the "Stargate SG-1" sequels, "" and "". "Camelot" was the first "Stargate SG-1" season finale since "Revelations" that was not intended to be the "SG-1" series finale, and the first one since "Exodus" that was a cliffhanger. The episode was written without the knowledge that "Stargate SG-1" would be picked up for a tenth season.
 Major Louis Ferretti, (played by French Stewart in the film as Lieutenant Louis Ferretti and Brent Stait in season 1) – A member of the United States Air Force and one of the four survivors of the first expedition through the Stargate in "Stargate". Ferretti joins O'Neill's team on another mission to Abydos in "Children of the Gods", and is put in charge of the SG-2 team after the death of Charles Kawalsky in "The Enemy Within". Ferretti makes his last appearance in "Within the Serpent's Grasp" to follow SG-1 through the Stargate, and is mentioned in season 3's "Shades of Grey" as a possible new leader of SG-1.
Stargate SG-1 spawned an industry of spin-off products. From 1999 to 2001, ROC published four Stargate SG-1 novels written by Ashley McConnell.[151] In 2004, UK-based Fandemonium Press launched a new series of licensed tie-in novels based on Stargate SG-1, although these books were unavailable in North America until 2006 when the license conflict with ROC expired.[152] Titan Publishing publishes the official Stargate Magazine,[26] while Avatar Press published a series of Stargate SG-1 comics.[26] British company Big Finish Productions began to produce Stargate SG-1 audio adventures in early 2008, voiced by members of the SG-1 cast.[153] A Stargate SG-1 roleplaying game and a Stargate trading card game were released in 2003 and 2007. Diamond Select Toys and Hasbro launched a series of toys in 2005 and 2006, respectively.[154][155] The planned video game Stargate SG-1: The Alliance was cancelled in 2005 and the futures of the MMORPG Stargate Worlds and the Third Person Shooter from the same studio (Cheyenne Mountain Entertainment) named Stargate Resistance were made clear in November 2010 following MGM's decision not to renew CME's Stargate license. Four amusement rides are based on Stargate– the Stargate SG-3000 theme park ride operating at Space Park Bremen in Germany and at Six Flags theme parks in Chicago, San Francisco and Louisville.[26]
According to Wright and Cooper, the worldwide popularity of science fiction was a factor in SG-1's success and the good international reception helped keep the series on the air in the beginning.[103] Several newspapers reported in 2005–2006 that Stargate SG-1 aired in over 100 countries with a weekly worldwide viewership of around 10 million,[26][86][103] but The New York Times gave different numbers in 2004, saying that the show was broadcast in sixty-four countries with more than 17 million viewers a week.[104] Stargate SG-1 had a particularly fervent response in the United Kingdom, Germany, France and Australia.[97][104]
Stargate SG-1 aired in the United Kingdom on Sky One with repeats on Sky Two, Sky Three and Channel 4. Sky One broadcast new episodes of the second half of most seasons before their American premiere. Brad Wright found it "almost embarrassing" that Stargate SG-1 was much more popular in the United Kingdom than in Canada,[26] where the show aired on Space, Citytv, A-Channel, Movie Central and French-language channels TQS and Ztélé.[96] Stargate SG-1 aired in Australia on Sci Fi Australia and Channel Seven. It aired in India on STAR World India and in Israel on Channel 1.
GateWorld was inaugurated on October 22, 1999 as "Starguide," a fan site that has changed addresses and servers many times since then. The site was developed by "SG-1" fan, Darren Sumner to be an online community for the show "Stargate SG-1", similar to web sites for other science fiction shows. Though the site focused on "Stargate", other parts of the site were devoted to other sci-fi series in the form of episode guides. It was during this time that Starguide was given the new name GateWorld. The main site was completely redesigned in 2006 to coincide with the broadcast of "Stargate SG-1"s milestone 200th episode. With the cancellation of "Stargate SG-1", Gateworld announced its support for SaveStargateSG1, a fan run campaign to get international networks and executives to show support for "Stargate SG-1" and to help get it back on the air.
ROC published four "Stargate SG-1" novels written by Ashley McConnell from 1998 to 2001. These novels were available only in the United States. The United Kingdom-based publisher Fandemonium specialises in "Stargate SG-1" and "Stargate Atlantis", publishing the first book in 2005. The "Stargate SG-1" novels were originally only available in the UK, Australia, New Zealand and South Africa because the company did not hold a licence to distribute them in North America but the "Stargate Atlantis" books are available worldwide. The company's license was later extended to North America in June 2006. All books are written as canon; that is, they try to recreate the show. MGM reads and approves all the novels.
Stargate: SG-1 Roleplaying Game is a role-playing game based on the TV series "Stargate SG-1", released in 2003 by Alderac Entertainment Group. The game, based on AEG's "Spycraft", uses the "d20 System". Since Sony did not renew AEG's contract to publish the game, it is now out of print.
Since SG-1's ratings were good from a financial standpoint, the Sci Fi Channel picked up MGM's offer to continue the show into a sixth season, yet with a slightly reduced budget.[71] Sci Fi aired new episodes of Stargate SG-1 in the 9 p.m. Friday slot between The Dead Zone and Farscape, while it aired older SG-1 episodes in a four-hour block every Monday at 7 p.m. Episodes were broadcast in US syndication six months after their premiere on Sci Fi.[32] The sixth season was supposed to be the show's last,[7] but Sci Fi renewed SG-1 at the last minute.[94] The sixth and seventh seasons made Stargate SG-1 Sci Fi's highest-rated original series with an average of 2 million viewers in over 1.3 million households,[95] elevating Sci Fi into the top 10 cable networks in the United States.[96] For the next few years, the producers believed each current season to be the show's last and repeatedly wrote big series finales,[86] but the success of Stargate SG-1 put off their plans of ending the show to write a new Stargate feature film.[97] Sci Fi cut the length of an SG-1 season from 22 to 20 episodes from Season 8 onwards.
Daniel Jackson, Ph.D., is a fictional character in the military science fiction franchise "Stargate", and one of the main characters of the series "Stargate SG-1." He is portrayed by James Spader in the 1994 film "Stargate", and by Michael Shanks in "Stargate SG-1" and other "SG-1" derived media. Jackson is the only "Stargate" character to appear in all of the films and series in the franchise (not including the non-canonical "Stargate Infinity"); the main character Jack O'Neill did not appear in the 2008 film "".
Stargate SG-1 spawned the live-action spin-off TV series Stargate Atlantis, the animated Stargate Infinity and the second live-action spin-off Stargate Universe. By SG-1's tenth season in 2006, Stargate SG-1 and Stargate Atlantis were said to have brought US$500 million in production to British Columbia.[26] MGM executive vice president Charles Cohen described Stargate SG-1 and its spinoff series as the television counterpart of their James Bond franchise, being very profitable and improving their image.[33]
"Stargate Atlantis" was supposed to be set on present day Earth, after "Stargate SG-1" was canceled. This cancelation of SG-1 didn't happen and "Stargate Atlantis" was released while "Stargate SG-1" was still airing, so the story arc was set in a new galaxy under the name, Pegasus. The story was set in another galaxy so the two running series would not collide with each other and to stop plot interferences.
"Stargate SG-1" is an American-Canadian military science fiction television series and part of MGM's Stargate franchise. The show was created by Brad Wright and Jonathan Glassner, based on the 1994 feature film "Stargate" by Dean Devlin and Roland Emmerich. The first five seasons of the television series were broadcast by Showtime before the series moved to the Sci Fi Channel for its last five seasons. "Stargate SG-1" premiered on Showtime on July 27, 1997; its final episode aired on Sky1 in the United Kingdom on March 13, 2007. "Stargate SG-1" was nominated for and won numerous awards in its ten-season run.
Later, McKay leaves and says goodbye to Carter while O'Neill talks with Hammond. They are then contacted by Teal'c, who informs them that the weapon was destroyed. Later, the gate from the Russians is installed and, although they want a Russian member at SG-1, O'Neill decides to take Jonas in, who then leaves with the team on his first mission.At the end of season 5, Michael Shanks (Daniel Jackson) decided to leave "Stargate SG-1" for concerns over being under-utilized. Some casting people from the SciFi Channel, who were looking to fill the void with a new character, happened to walk through the courtyard of MGM's Santa Monica offices where Corin Nemec was that day. They briefly mentioned "Stargate" to him, and the same afternoon Nemec's manager called Nemec to tell him they were interested in him. Since Nemec had never watched "Stargate SG-1" up until that time (he was familiar with the "Stargate" film though), he was sent some videotapes of the show and had some more meetings until he was finally cast as Jonas Quinn for the penultimate season 5 episode "Meridian". Everyone agreed to wait and see how the character looked on film before deciding on long-term involvements, but MGM liked what they saw. Although "there's been quite a bit of ire directed by fans towards Daniel's replacement" after the airing of "Meridian", Robert C. Cooper hoped that they would like the character in the end.
The first season of the military science fiction television series "Stargate SG-1" commenced airing on the Showtime channel in the United States on July 27, 1997, concluded on the Sci Fi channel on March 6, 1998, and contained 22 episodes. The show itself is a spin-off from the 1994 hit movie "Stargate" written by Dean Devlin and Roland Emmerich. "Stargate SG-1" re-introduced supporting characters from the film universe, such as Jonathan "Jack" O'Neill and Daniel Jackson and included new characters such as Teal'c, George Hammond and Samantha "Sam" Carter. The first season was about a military-science expedition team discovering how to use the ancient device, named the Stargate, to explore the galaxy. However, they encountered a powerful enemy in the film named the Goa'uld, who are bent on destroying Earth and all who oppose them.
Since Stargate SG-1 was expensive to produce, MGM arranged an agreement with Showtime that SG-1 could air in syndication six months after their premiere on Showtime.[90] All 22 Fox stations aired the first seasons after their Showtime debut, providing a clearance of 41% of the United States.[91][92] The Sci Fi Channel made its largest single programming acquisition of $150 million in 1998 by buying the exclusive basic cable rights to the MGM package Stargate SG-1, The Outer Limits and Poltergeist: The Legacy.[93] Showtime decided to end its association with Stargate SG-1 at the end of Season 5, saying that the show still had a sizeable viewership but could no longer draw new subscribers due to its availability in syndication.[33]
The main setting of Stargate SG-1, the fictional Stargate Command (SGC) at the (real) Cheyenne Mountain Air Force Station near Colorado Springs, Colorado, was filmed at stage 5 of The Bridge Studios.[31] Martin Wood filmed half a dozen stock shots of the real Cheyenne Mountain complex for use in the series approximately ten days before the premiere of the pilot episode. Although these shots wore out over the years, the producers did not film new shots until the beginning of Season 9, thinking that Stargate SG-1 would be cancelled after each current year.[35][36] By then, visitor questions and fan theories about the existence of a Stargate at the real Cheyenne Mountain complex had become so common that Cheyenne Mountain had installed a seemingly high-security door labeled "Stargate Command" for one of their storage rooms holding brooms and detergent.[37]
Stargate SG-1 has had several opening title sequences, which are generally preceded by a teaser act. The credits are normally sixty seconds long. Richard Dean Anderson was the only SG-1 actor whose name appeared before the show's title. Michael Shanks' name was moved near the end of the opening credits with the appendage "as Daniel Jackson" after his return to the show in Season 7. Some DVD versions of early SG-1 seasons have different opening credits from the television versions, as do the direct-to-DVD films. Composer Joel Goldsmith adapted David Arnold's Stargate feature film score for SG-1's opening title theme, which remained the same during the run of Stargate SG-1 and its direct-to-DVD films.
