Huge ratings for Ghost Hunters and Battlestar Galactica: Razor helped the Sci-Fi Channel achieve its best November ever among young adults and total viewers (1.13 million). More female viewers are migrating to the out-there cabler, too: viewership among women 18-34 and 18-49 is up 11 percent and 6 percent, respectively. Hunters broke series and network records on Wednesdays with a weekly average of 2.1 million viewers for the season. It’s the best season yet for the show about plumbers who hunt for ghosts at night (yep, you read that right). The Nov. 24 premiere of Razor averaged a respectable 1.7 million viewers.
