'Category 7' lifts CBS to seventh weekly win

Solid showings from most of its drama series and the disaster mini "Category 7: The End of the World" propelled CBS to another double weekly victory, extending the network's winning string to seven weeks in total viewers and four in adults 18-49. Seven weeks into the 2005-06 broadcast season, CBS and ABC are tied among the 18-49 demographic with a 4.0 rating/11 share. For the week ending Oct. 31, which included the first four nights of the November sweep, CBS averaged 13.4 million viewers and a 4.1/11 among adults 18-49, according to Nielsen Media Research data
