Sci Fi Channel has commissioned a record-setting 10th season of Friday-night centerpiece drama Stargate SG-1 and ordered up a third season of spinoff drama Stargate Atlantis.
Production on both 20-episode seasons is scheduled to begin early next year, aiming for summer premieres on the channel. Both air on Fridays, ahead of Sci Fi hit Battlestar Galactica, which the network has not yet renewed, according to a spokeswoman.
SG-1 -- which started out on Showtime before shifting to NBC Universal Cable’s Sci Fi -- is now the longest-running science-fiction drama in U.S. television history, the network said. The X-Files ran for nine seasons.
SG-1’s ratings actually rose this past season, averaging 2.4 million viewers per week over the first half, despite major cast changes in season nine, including the departure of star Richard Dean Anderson. Ben Browder, Beau Bridges and Louis Gossett Jr. joined the cast in season nine.
SG-1 co-creator Brad Wright and Robert C. Cooper will return as executive producers on both shows.
SG-1 is produced by Double Secret Productions, with Metro-Goldwyn-Mayer Inc. and Sony Pictures Television. Atlantis is produced by Acme Shark, with MGM and Sony.
