Thursday's ratings rundown:
Survivor scored a seven percent week-to-week increase to top the hour with 13 million total viewers. With an audience of 9.2 million, Ugly Betty, too, was up (250K). NBC's Earl flirted with seven mil (up 370 thou), but lead-out Kath & Kim (five mil) saw its audience clipped by a half mil. Behind Kitchen Nightmares, Smallville dipped a hair to 4.38 mil, but the CW's numbers for the night are tainted by a New York City-area/Jets preemption.
CSI surged 830K to come out to yet again claim No. 1 with nearly 19 million viewers. Grey's (15.6 mil) topped the demos. The Office slipped to a new season low of 8.18 mil, and 30 Rock (7.5 mil) saw 490,000 Friends go away. Supernatural tacked on 710 thou to hit 3.91 mil. (But again, J-E-T-S.)
Eleventh Hour gained 700K to dominate with 11.7 million viewers, perhaps popping its "bubble" status once and for all. ER's fab flashback episode delivered a 13 percent bump, to 9.8 mil — the long-running series' largest audience in more than a year. Life on Mars held steady at 8.94 mil.
