President Bush Can't Ruin Grissom's CSI Goodbye

William Petersen's last episode as series regular watched by 24.2 million on Thursday; The Office, Grey's Anatomy hold up OK in ratings

Thursday TV's Big Wrench in the Works: President George W. Bush. Yes, the farewell address is a tradition for the outgoing commander in chief, but wasn't it President Dwight Eisenhower who warned about the dangers of delivering one on William Petersen's farewell night on CSI?

How Did Bush Mess With CSI Exactly? Because of the Bush speech, the CSI repeat that aired at 8 p.m. bled into the new CSI at 9 p.m., and the new CSI bled into Eleventh Hour at 10 p.m. It took a few hours, but CBS finally sorted out the numbers: Petersen's last CSI (as a regular, that is—Gil Grissom did live, after all) was watched by 24.2 million. The show scored its biggest audience since its season eight premiere in fall 2007, CBS said, and easily won the night in total viewers and adults 18-49.

What About Patrick Swazye's Show? Through no fault of President Bush's, A&E said it wouldn't have estimates on the premiere of The Beast till the afternoon—at the earliest.

Which 9 p.m. Show Lost Out—Grey's Anatomy or The Office? Neither.

ABC's Grey's (13 million, Nielsen estimates showed) continued to slide in total viewers, but held steady in adults 18-49, even as CSI took first in that demo. Among women 18-34, it was dominant.

In its first new episode after winter break, NBC's The Office (8.3 million) was up a tad over its season average, and got a bunch of 18- to 34-year-old guys to watch the culmination of the Andy-Angela-Dwight love triangle. It also won its time slot among adults 18-34.

30 Rock Watch: Up from last week (6.6 million viewers versus 5.2 million); down about 25 percent in the 18-49 demo and about 32 percent in the 18-34 demo from The Office. In short, it's had far, far worse nights.

Strength in Numbers: The introduction of Cosmic Boy and other Legion of Superheroes members helped lead CW's Smallville (4.3 million) to its biggest audience since early November, the network said. The show also did its anti-Gossip Girl thing, and won the 8 p.m. hour in men 18-34.

Also-Rans: ABC's Private Practice (8.7 million), NBC's ER (7 million), NBC's My Name Is Earl (6 million) and the CW's Supernatural (3 million). CBS' Eleventh Hour (13.2 million) was the most-watched show after CSI mostly on account of it aired after CSI.
