Two NBC comedy series had their lowest-rated finales ever Thursday night, as the trend on most of the broadcast networks was down, TVbytheNumbers.com reports.

According to Nielsen overnights, NBC’s “The Office” scored a modest 2.2 average rating in the key 18-49 demo — the show’s lowest-rated season finale ever. The number was also down one-tenth of a ratings point from last week’s 2.3.

NBC’s “Parks and Recreation” also had its lowest season finale, pulling a 1.7 in 18-49.

That was better than most of the NBC lineup, as the Peacock found itself in familiar territory with a distant fourth-place finish for prime time overall. “Community” managed a 1.4 in the 18-49 demo, “30 Rock” drew a 1.5 — an improvement from last week’s 1.4 — and the network’s 10 p.m. drama “Awake” managed a modest 0.9, up two-tenths from last week.

Programming on other broadcast networks also struggled. ABC’s “Missing” fell to a series-low 1.1 average rating in 18-49, while “Grey’s Anatomy” was up one-tenth to a 3.4 and “Scandal” climbed one-tenth to a 2.0. Fox’s “American Idol” fell off one-tenth from last week to a 3.9, while “Touch” held steady with a 2.0.

CBS had the distinction of the night’s top program, “The Big Bang Theory,” even though the show was off a whopping five-tenths of a ratings point from last week. “Bang” pulled a 4.2 in viewers 18-49, down from last week’s 4.7.

Elsewhere on CBS, “Rules of Engagement” held even with a 2.7 in 18-49, “Person of Interest” ticked up a tenth to a 2.6 and “The Mentalist” slipped one-tenth to a 2.4.

For prime time overall, Fox got the win in 18-49 by a narrow margin over CBS, while CBS edged ahead in total viewers. In adults 18-49, Fox led with a 2.9 average rating to CBS’s 2.8, ABC’s 2.2 and NBC’s 1.4. Total viewers saw CBS out front with 12.1 million to Fox’s 11.0 million, ABC’s 7.5 million and NBC’s 3.2 million.
