While no one was looking, Stargate SG-1 (starring Ben Browder, Christopher Judge, and Claudia Black) become the longest-running sci-fi series in American TV history, now that SciFi Channel has renewed it for a 10th season. (SciFi has also renewed spinoff Stargate Atlantis for a third season.)

Anyone know what the longest-running sci-fi show on our planet is? (I’m guessing it’s Dr. Who.) And does anyone want to explain to the group what’s behind the longevity of SG-1? My theory: That MacGyver guy can do anything.
