Beginning April 12th, 30 Rock is changing time slots with Scrubs.
30 Rock is being pushed up to 9:00 p.m., while Scrubs will be moved down to 9:30 p.m. NBC’s reasoning for the move appears to based on the theory that 30 Rock will be more compatible with The Office and thus hold more viewers. Since Scrubs has a loyal fan base (now in its sixth season), it doesn’t necessarily require a strong lead-in to perform well.
The 30 Rock/Scrubs pairing will not go into effect until April 19th (the week after the time period premiere of 30 Rock). This is because the new comedy Andy Barker, P.I. will be running from March 15th to April 12th in the 9:30 to 10:00 p.m. time slot.
Lastly, on the night of 30 Rock’s return, NBC will have supersized episodes of all their comedies.
From the NBC Press Release:
On April 5, NBC’s super-sized lineup will include (times approximate): “The Office” (8-8:40 p.m. ET); “30 Rock” (8:40-9:15 p.m. ET); “Scrubs” (9:15-9:50 p.m. ET); “Andy Barker, P.I.” (9:50-10:20); and an encore episode of “My Name Is Earl” (10:20-11 p.m. ET).
