NBC has renewed its long-running comedy 30 Rock for Season 7, which will also be the show's last. The network has ordered 13 more episodes to conclude the series.
While dropping ratings may have factored into the decision - this season's numbers have been about 60% lower than last - it was likely that cast members are wanting to move on from the show and leave on a high note. In April of last year, co-star Alec Baldwin told New York Magazine's Vulture Blog that the show was ending this year, but now it appears that one final season has been agreed upon by all parties.
