SG1

SG-1 is an American-Canadian science fiction television series created by Brad Wright and Jonathan Glassner, continuing the story of the 1994 film Stargate. It follows the Stargate Command (SGC) at the Cheyenne Mountain complex as they develop and operate the Stargate to travel to other worlds. The main team SG-1 consists of Colonel Jack O'Neill, Dr. Daniel Jackson, Captain Samantha Carter, and Teal'c, a Jaffa warrior who defects from the Goa'uld. Over the series, the lineup changes with Daniel briefly replaced by Jonas Quinn for a period and later additions including Cameron Mitchell and Vala Mal Doran. The team encounters various alien civilizations, including the Goa'uld, the Replicators, the Asgard, and the Tok'ra, guiding Earth through alliances and conflicts.

The show blends military science fiction with mythological and ancient-astronaut themes. It popularized long-form story arcs, recurring villains, and a blend of episodic adventures with serial developments. The Goa'uld served as primary antagonists early on, while more complex threats emerged in later seasons. The program was produced by MGM Television and distributed by MGM Worldwide Television Distribution, airing in the United States on Showtime for the first season and then primarily on the Sci-Fi Channel (now Syfy) from 1998 onward, concluding after ten seasons and 214 episodes in 2007. The success of SG-1 helped spawn Stargate Atlantis (2004–2009) and contributed to the wider Stargate franchise.

Reception and legacy: SG-1 received generally positive reviews for its expanding universe, character dynamics, and humor, though pacing and scientific accuracy were variable. It built a dedicated fan base and influenced later sci-fi series with serialized elements. The series has had lasting influence through home media, syndicated reruns, and continued interest in the Stargate universe.
