'Community' Ratings: Season 4, Episode 2 Has Drastic Drop

"Community" ratings took a sharp drop during its second week of Season 4.

Preliminary numbers for "Paranormal Parentage" had the NBC comedy pulling in 2.8 million viewers and a low 1.1 rating in the 18-49 demographic. The Season 4 premiere, which aired on Thursday, Feb. 7, had nearly 4 million viewers and a 1.8 rating in the 18-49 demographic, a solid number for NBC.

On CBS, "The Big Bang Theory" had 17.6 million viewers and a 5.4 rating, while Fox's "American Idol" had 12.3 million viewers and a 3.6 rating. Over on ABC, the Anthony Edwards vehicle "Zero Hour" premiered to 6.3 million viewers and a 1.3 rating and The CW's "The Vampire Diaries" brought in 2.3 million viewers and had a 1.0 rating.

Chalk it up to Valentine's Day, bad promotion or whatever makes you feel better, but the low numbers certainly pushed "Community" even further onto the cancellation bubble. However, the show's ratings will likely go up when DVR views are counted.

It hasn't been an easy go of it for "Community," which has made headlines for all the wrong reasons over the past year. Backstage drama between creator Dan Harmon and actor Chevy Chase, Harmon's departure and then Chase's departure didn't translate into more viewers.

"Community" airs on Thursdays at 8 p.m. EST on NBC.
