A trio of comedies had their last episodes of the season Thursday night, and here’s how they ranked:

Big Bang Theory (13.3 million, 4.2 adults 18-49 rating) not only won its time slot, but led the night. The sitcom was down 11 percent this week, but winning the evening is a fitting finish for a show that managed to become the first entertainment program to regularly topple American Idol (a steady 15.1 million, 3.9 rating last night).

On NBC, The Office (4.4 million, 2.2) closed its doors for the season. The show was down 4 percent this week and ranked as the comedy’s lowest-rated finale ever. The Dunder Mifflin gang will get a renewal, probably today, but faces a bumpy future, with some fans feeling like the show is creatively tapped out.

Parks and Recreation (3.5 million, 1.7), however, still feels the love from fans, though NBC wishes there were more of you watching. The finale was unchanged from last week. We’re expecting a Parks renewal for 13 episodes, probably today.

Other Thursday ratings highlights:

— Two of ABC’s freshman midseason shows seemed poised for different fates. Neither Missing (6.4 million, 1.1) nor Scandal (6.5 million, 2.0) was on the network’s first list of renewals last night. Missing fell 8 percent to a series low, while Scandal was up slightly. We expect Scandal will get another shot.

— Another bubble drama, NBC’s Awake (2.5 million, 0.9) rose in the ratings this week, but was also the night’s lowest-rated show on a major network. We don’t expect a pickup.

— The CW’s Secret Circle (1.2 million, 0.5) also still hasn’t been picked up yet. Last night’s finale was down a tenth of a point and shed a ton of its Vampire Diaries lead-in (2.5 million, 1.1). Our prediction: Squeaking into a renewal next week and a move to Friday nights next season.
