CBS bagged the most viewers last week, Fox snared the most young viewers, but ABC enjoyed the most water-cooler talk.
Here's a look at the week's ups and downs:
"Desperate Housewives." Against all odds, this serialized drama starring middle-aged women and airing on ABC remains the No. 1 new show of the season. Last week it copped nearly 21 million viewers -- its biggest haul since its unveiling. And though it aired opposite Game 4 of the American League playoffs, "Housewives" continued to score with men. It was the week's No. 2 series among 18-to-49-year-old guys, behind only "Monday Night Football," and beat every night of baseball on Fox.
"Lost." ABC's other new drama also drew its biggest crowd since its premiere -- more than 18 million viewers. That made ABC the go-to network for the presidential debate immediately after. ABC logged 14.5 million viewers for Wednesday's debate -- more than any other network.
Bob Schieffer. More than 51 million viewers watched the third presidential debate, moderated by CBS News's Schieffer. That's about 5 million more than watched the second debate the previous week, and nearly 14 million more than watched the third debate between George W. Bush and Al Gore in 2000.
"Crossing Jordan." Heading into the Sunday 10 p.m. hour, ABC's "Boston Legal" had a 9-million-viewer advantage over NBC's "Crossing Jordan." Yet "Jordan" beat "Boston" by about 1.4 million.
"Last Comic Standing." NBC dumped the final episode of this reality series, in which the winner of the standup-comic competition would be revealed. Comedy Central, which had been rerunning each episode, said it would telecast the finale. NBC then tried to do them wrong by posting the winner on its Web site before the episode played on the cable net. Even so, the finale clocked 731,000 viewers Saturday -- a hefty hike from the show's Comedy Central average of about 436,000.
"Trading Spaces." A renovated "Trading Spaces" returned to TLC for its fifth season last Saturday but dusted up only 1.8 million viewers. Last season, the show opened with 3.3 million.
"Law & Order: Criminal Intent." Stunt allowing viewers to vote online whether Detective Goren's nemesis Nicole Wallace lives or dies did not move the ratings needle on NBC's Sunday drama. Last week's episode logged 11.9 million viewers, lower than the previous week's 12.8 million.
"Manhunt: The Search for America's Most Gorgeous Male Model." Only 453,000 viewers bothered to check out the debut of Bravo's self-explanatory reality series Tuesday, even though its lead-in, an abbreviated version of Maria Shriver's NBC interview with Siegfried & Roy, handed it an audience of 1.2 million.
"Hope & Faith." Last season at this time, Kelly Ripa's ABC sitcom looked like a hit, averaging more than 10 million viewers on Fridays. Last week it was down to 6 million.
The week's 10 most watched programs, in order, were CBS's "CSI" and "CSI: Miami"; ABC's "Desperate Housewives"; CBS's "Without a Trace" and "Survivor: Vanuatu"; ABC's "Lost"; CBS's "Everybody Loves Raymond" and "Two and a Half Men"; NBC's "ER"; and CBS's "60 Minutes."
