Thursday's ratings rundown:
Survivor topped the hour with a typical 12.8 million total viewers, followed by Ugly Betty (8.47 mil). Placing third, My Name Is Earl dropped 10 percent week-to-week to hit 6.09 mil (it's second-smallest audience of the season), while lead-out Kath & Kim (4.88 mil) toppled 11 percent.
CSI (17.4 million viewers) and Grey's Anatomy (15.15 mil, No. 1 in demos) both dipped five percent. NBC's The Office (8.34 mil) and 30 Rock (7.14 mil) also slipped a bit.
Barbara Walters proved to be especially fascinating, delivering an audience of 13.2 million viewers - most of whom, I must assume, had you-know-who pegged for the No. 1 spot. Eleventh Hour placed second with 10.9 mil (showing a slight uptick from its previous outing), while ER (8.23 mil) dropped 10 percent.
