The New Orleans Saints’ victory over the Indianapolis Colts may have scored one for the record books for CBS, according to preliminary results from Nielsen Media. The overnight results put the live viewership at an estimated 96.5 million, up 7.3 million over last year’s comparable preliminary numbers, the highest rating in 23 years — and likely to break the 100 million-mark once numbers are finalized and time-delayed viewership is added in. The high numbers were, of course, a boon to CBS’ airing of reality show Undercover Boss, whose 38.1 million viewers make it the best-rated post-Super Bowl airing since 2006’s Grey’s Anatomy.
