Grissom's the victor in battle of bye-byes


Thursday night's ratings were marked by the farewells of George W. Bush and Gil Grissom, with the president's farewell address drawing fairly average viewership and William Petersen's final episode of "CSI: Crime Scene Investigation" attracting a huge crowd.

Petersen's last appearance as a regular cast member on CBS' "CSI" was seen by 24.3 million viewers, the series' largest audience since the show's 2007 season premiere. "CSI" received a 6.6 adults 18-49 rating and a 16 share. Later, "Eleventh Hour" (13.2 million, 3.4/9) also performed well, posting its second-largest audience of the season.

Bush's live address totaled a 20.9 metered-market household rating across four networks. That's in the ballpark of 25 million- 33 million viewers and doesn't count cable news coverage.

ABC's "Grey's Anatomy" (13.1 million, 5.3/12) was up a notch from its previous series-low original, and "Private Practice" (8.5 million, 3.3/8) maintained its debut retention of the "Grey's" audience.

NBC's "The Office" (8.5 million, 4.4/10) and "30 Rock" (6.6 million, 3.2/8) were on par, with "ER" (7 million, 2.7/7) on the low side.

Fox had a modestly rated second-season finale for "Kitchen Nightmares" (4.4 million, 2.0/5) at 9 p.m.

On the CW, "Smallville" (4.3 million, 1.8/5) had its best performance since November, followed by "Supernatural" (3 million, 1.2/3). (partialdiff)
