It was announced at yesterday's (May 14) upfront presentation that the forthcoming seventh season of the Tina Fey sitcom will be its last.
NBC entertainment chief Robert Greenblatt also confirmed that the final ever episode will be extended to 60 minutes.
"I know Tina, Alec Baldwin and the rest [of the cast] will deliver some of their best work," TV Line quotes him as saying. "We think the world of Tina."
There had been confusion over the future of 30 Rock when NBC backtracked on its initial claim that the show would conclude after seven seasons.
Fey admitted back in April that she could see the end of 30 Rock "on the horizon".
