November's Must-Sweeps TV

This fall, the broadcast networks have their own heated race: November sweeps. Going into the season's first sweeps period, Nov. 4-Dec. 1, the Big Four broadcasters were locked in a ferocious battle for the advertiser-rich 18-49 demo. Nielsen reports that Fox is in the lead (4.1 rating), but CBS is within striking distance (4.0) and third-placed NBC and ABC (each with 3.8), are close on their heels for the first six weeks of the TV season.

“One break could swing the race,” says Kelly Kahl, CBS senior vice president of operations. To tip the scales, the broadcasters are readying big guns, including theatricals Shrek and Harry Potter and the Sorcerer's Stone and fabulous guest stars like teen queen Lindsay Lohan and Sex and the City siren Kristin Davis. They're also luring viewers with scheduling ploys, producing connected episodes of NBC's Las Vegas and Crossing Jordan, UPN's America's Next Top Model and Kevin Hill. An added bonus: a two-parter of CBS' Without a Trace. Here's a rundown of each network's November surprise:
