NBC has announced it is picking up Tina Fey's sitcom "30 Rock" for a full season.
30 Rock follows the fictional NBC series 'The Girlie Show', an SNL-type sketch show. Fey plays head writer Liz Lemon, who butts heads with new network overlord Jack Donaghey (Alec Baldwin).
Donaghey's first move as Girlie Show boss is to hire unstable comedian Tracy Jordan (unstable comedian Tracy Morgan).
The new show has struggled in the ratings but the other night's episode in a new Thursday night timeslot rose from its season average by 25 percent.
