"30 Rock" will run for 13 episodes for its seventh and final season, the network said at its upfront presentation Monday. The series will also run a one-hour series finale.
NBC Entertainment chairman Robert Greenblatt also said that "30 Rock" creator Tina Fey will remain involved with the network in some capacity long after the show is gone.
News broke that "30 Rock" had been renewed last week, along with word that the comedy "Parenthood" will return for another season.
"30 Rock"'s current season has averaged a 2.1 rating in the advertiser-cherished 18-49 demographic.
