Nine More for '30 Rock'

NBC's remade Thursday comedy lineup, which debuted last night, will remain intact for a while.

The network has given a full-season order to "30 Rock," the lone freshman series in the group, following a fairly decent ratings performance in its new time period. It becomes the fourth new NBC show to be picked up this season, following "Heroes," "Studio 60" and "Friday Night Lights."

"In '30 Rock,' [creator/star] Tina Fey and [executive producer] Lorne Michaels, along with stars Alec Baldwin and Tracy Morgan, have the goods with this excellent comedy," NBC Entertainment boss Kevin Reilly says. "We look forward to future episodes of this bright new show, which is right on-brand for our Thursday-night comedy block."

Like "Studio 60," "30 Rock" is set behind the scenes at a sketch comedy show. It focuses on the fictional show's head writer, Liz Lemon (Fey), whose life is thrown into chaos by the arrival of a new NBC executive (Baldwin), who bullies her into hiring a mercurial movie star (Morgan) onto her show's cast.

Jane Krakowski, Scott Adsit, Jack McBrayer and Judah Friedlander also star in the series.

The pickup comes one day after "30 Rock" made its time-period debut at 9:30 p.m. ET Thursday night. It drew about 6 million viewers -- on par with its season average -- and a 2.7 rating among adults 18-49, better than its season-long nubmer of 2.4. It retained about three-fourths of the audience from its lead-in, the season premiere of "Scrubs" (7.7 million viewers, 3.6 in adults 18-49).
