TV Ratings: 'Person of Interest' Grabs Largest Audience Since Debut, 'Prime Suspect' Hits Series Low
As the holidays loom, television viewing was down compared to the previous week.
CBS' Person of Interest (12.8 million total viewers, 2.8 rating in adults 18-49 demographic) scored an impressive uptick in total tune-in, drawing the largest audience since the rookie drama's series premiere in September. But in the demo, Interest remained steady with its last original, down three-tenths from the debut (3.1 vs. 2.8). The J.J. Abrams procedural helped CBS take the victory, averaging a 2.8 in primetime.
With Big Bang Theory (10.1 million, 2.8) showing a repeat, Rules of Engagement (9.7 million, 2.7) fell 10 percent and is a season low. An original episode of The Mentalist (13 million, 2.7) remained steady from its last episode, like Interest.
The X Factor's (9.7 million, 2.8) top four results show dipped only 3 percent versus last Thursday. In the younger adults 18-34 demo, the reality competition series saw a 5 percent improvement (2.2 vs. 2.1). Fox aired an encore of Bones (5.4 million, 1.5). All told, the network ranked second among adults 18-49 but was the top broadcast player in 18-34 for the night.
ABC placed third with a repeat of A Charlie Brown Christmas (6.4 million, 1.8), down 5 percent from last year's telecast (1.9 vs. 1.8). Katie Couric's two-hour year-end special (5.5 million, 1.5) couldn't win its 8 or 9 p.m. hours.
With NBC's comedy block all in reruns, it didn't boost Prime Suspect (3.6 million, 0.8) in any capacity, with the Maria Bello reboot plunging a drastic 38 percent from two weeks ago to hit a new series low.
