Airlock Alpha has a feature on the sci-fi genre shows, according to which, "Of the seven genre shows that returned from the strike-shortened 2007-08 season, only one grew its audience last year."
The only program to actually see a jump in ratings this year was "Supernatural" on The CW, growing 10.5 percent in average overnight ratings from a 1.9 rating/3 share in 2007-08 to a 2.1/3 last season. Its companion show, "Smallville," dropped nearly 8 percent from a 2.6/4 to a 2.4/4. Both "Supernatural" and "Smallville" were renewed by The CW, but the network has already announced they will not be paired up next year.
