"Stargate SG-1" is a seminal science fiction television series that aired from 1997 to 2007, with a total of 10 seasons and 214 episodes. The show was created by Jonathan Glassner and Brad Wright and served as a sequel to the 1994 film "Stargate." The series follows the adventures of SG-1, a military team from Earth, as they travel through a network of ancient alien transportation systems known as Stargates to explore the galaxy, encounter various alien civilizations, and defend Earth against threats from other worlds. The show begins with the discovery of a Stargate, an ancient alien device that allows for near-instant travel to other planets across the galaxy. The Stargate is a circular device with a series of symbols around its perimeter, which must be entered in a specific sequence to dial a specific planet. The series focuses on SG-1, a team initially consisting of Colonel Jack O'Neill (Richard Dean Anderson), Dr. Daniel Jackson (Michael Shanks), Dr. Samantha "Sam" Carter (Amanda Tapping), and Teal'c (Christopher Judge), a Jaffa warrior from the planet Tau'ri's homeworld.
The series finale aired on June 13, 2007. Following the conclusion of "SG-1," the franchise continued with "Stargate Atlantis" and "Stargate Universe," though the focus shifted to different characters and settings. Despite ending its original run in 2007, "Stargate SG-1" remains popular and continues to be celebrated by fans worldwide for its contributions to science fiction television.
The show is well-regarded for its positive portrayal of strong, intelligent characters, particularly women and people of color, in leading roles. It also explores complex moral and ethical dilemmas, making it more than just a simple space opera.
