Ratings: Rob Astounds in Its Debut; The Finder Gets Lost in the Shuffle

The Animal and Deuce Bigelow fans, unite! Rob Schneider's new sitcom delivered astounding numbers, both in viewership and within the industry-standard 18-to-49 demo, according to preliminary Nielsen data.

" Muy bueno!" CBS crowed, noting that Rob delivered the biggest audience and demo rating in the time period since May 2010. Helping, of course, was The Big Bang Theory'sbiglead-in.

Following the two comedies, Person of Interest posted series highs in all measures.

Consequently, NBC's quartet of sitcoms got stomped. The return of 30 Rock was met with a demo rating 31 percent lower than last year's debut. The good news? Parks and Recreation rose 13 percent, while The Office demo was even and Up All Night up 5 percent vs. their respective previous first-run outings. Worst of all, The Firm — which got off to the worst start ever for an NBC regular-season drama on Sunday — did even worse the second time (in what was planned to be its regular Thursday time slot), plummeting some 30 percent.

Relatively lost amidst all this: The Finder, which premiered weakly in prime time's middle hour. But, next week, it follows American Idol.
