More alarming ratings news for NBC. (And the network has had a ton of those lately – it just got beaten by USA on Monday!) Despite airing reruns of rookies Prime Suspect and Whitney on Monday and Wednesday this week to get additional sampling and boost the ratings for the originals, the opposite happened last night. Both series were down 13% week-to-week in the 18-49 demographic to a 2.0/5 and 1.3/3 among adults 18-49, respectively. That despite the extra exposure (NBC also is running Whitney and Prime Suspect repeats on Friday and Saturday) and the fact that all other NBC series that preceded the two freshmen were up — Community (1.7/5, up 13%), Parks & Recreation (2.1/6, up 5%), The Office (3.2/8, up a tenth).
