Tina Fey starrer to follow 'Office' at 9:30 p.m.
NBC is giving “30 Rock” a major timeslot upgrade, shifting the Tina Fey starrer to 9:30 Thursdays starting this week.“Rock,” which has been airing at 8:30 p.m., will now benefit from having the Peacock’s red-hot laffer “The Office” as its lead-in. “Scrubs” will inherit “Rock’s” earlier timeslot. Slot switcheroo is a no-brainer. “Rock” has been renewed for next season and is a key part of NBC’s sitcom strategy going forward. “Scrubs,” meanwhile, will air its final NBC episode in a few weeks. Peacock execs rightly figured it made sense to use the final few weeks of the season pumping up “Rock.” NBC brass are also trying to capitalize on the pre-release hype surrounding “Baby Mama,” which Fey toplines.
