The Big Bang Theory-American Idol battle for ratings supremacy on Thursday produced another tie. Both shows repeated their fast national 18-49 rating from last week, 5.4, to share the No. 1 demo spot for the night for a second consecutive week. In direct competition from 8-8:30 PM, Big Bang (16.4 million total viewers) once again topped the Fox reality series in 18-49 and total viewers and drew its largest audience ever on the opening night of the February sweep.
After an encouraging 32% ratings jump last week, Fox’s The Finder was down 14% to a 2.4/6 as it faced an original Grey’s Anatomy, Person Of Interest and The Office vs. repeats last week. Fox (3.9/11) won the night in 18-49. Following Big Bang, freshman Rob (3.4/9) shed another tenth week-to-week. But it is certainly helping Person Of Interest (3.3/9), which posted a series high in 18-49 (the series also posted a 3.3 in the fast nationals two weeks ago before being adjusted down to a 3.2). The rookie drama has now tied or posted a series high all three times it has aired an original after Rob. At 10 PM, The Mentalist (2.8/8) was down 7% from 2 weeks ago.
ABC’s Wipeout (1.8/5) was flat with two weeks ago to tie a series low. Ditto for the special alternate universe episode of Grey’s Anatomy (3.5/9). Private Practice (2.3/6) was up 10% from two weeks ago.
As for NBC … Let’s start with the good news. Parks And Recreation (1.8/5) was up 6% from last week. Now the four bad ones: 30 Rock (1.3/4) was down 19% from last week for a series low. The Office (2.7/7) was down 10% from two weeks ago to a season low and the series’ lowest Thursday rating ever. Up All Night (1.8/5) was down 5% from two weeks ago, and The Firm (0.8/2) dropped 20% to a new series low. The CW’s Vampire Diaries (1.2/3) was up a tenth from two weeks ago. The Secret Circle (0.7/2) was even.
