Ratings Chart Attack!

There’s no party like a Lemon party, as “30 Rock,” riding the wave of publicity surrounding Tina Fey, took in a series-high rating for its third-season premiere.

Drawing a 4.1 rating/10 share in the 18- to 49-year-old demographic, “30 Rock” improved 21% over its premiere last year, according to preliminary Nielsen Media Research data.

“The Office” (4.7/12) and “Kath and Kim” (2.3/6) grew a respective 12% and 5% week-to-week, while “My Name Is Earl” (2.4/7) matched its lowest original episode rating ever.

“ER” also increased 6% week-to-week to a 3.4/9.

Despite the increases, NBC placed third for the night with a 3.4/9.

Nightly winner CBS, with a 3.9/10 and 14.4 million viewers, had its entire lineup of “Survivor” (4.1/12, 13.3 million), “CSI” (4.7/11, 19.5 million) and “Eleventh Hour” (2.9/8, 11.8 million) hit season lows in adults 18-49. “CSI” matched its lowest original Thursday rating ever, excluding Thanksgiving.

But for those keeping score at home, CBS does capture the first night of November sweeps in total viewers and adults 18-49.

ABC’s “Ugly Betty” (2.5/7) also netted a season low, declining 11%. “Grey’s Anatomy” (5.5/14) crept up a tenth of a percentage point, while “Life on Mars” (2.7/7) moved the needle up 13%. ABC ended the night with a 3.6/10.

Fox tied for fourth with The CW, drawing a 1.6/4, on the back of an original “Kitchen Nightmares” (1.7/4). The CW’s “Smallville” (1.7/5) stayed flat, while “Supernatural” (1.5/4) increased by 15%.
