American Idol, The Big Bang Theory, Grey's Anatomy, The Office, and The Mentalist were each adjusted up a tenth with adults 18-49 vs. the Thursday preliminary numbers. Rob was adjusted down a tenth of a point.
Here's some interesting info from NBC on last night's 30 Rock:
Ratings for the February 2 telecast of "30 Rock" were apparently impacted by an episode description that matched the description of the prior week's 9 p.m. telecast, resulting in some DVRs failing to record the program though it was correctly listed as an original. NBC Research estimates that had the telecast received the level of time-shifted viewing seen in the time period over the prior three weeks, its "live plus same day" adult 18-49 rating likely would have been a 1.5 rather than last night's 1.3. NBC Research and Scheduling say correct information was issued by the network but technical issues caused some listings to inaccurately carry the same episode descriptions for January 26 and February 2.
