NBC has had some low-rated series premieres in its day — last year’s short-lived “Paul Reiser Show” comes to mind. But TVbytheNumbers.com reports that last night’s series premiere of the comedy “Bent” set a new low mark for the network, pulling a 1.0 rating in adults 18-49 — the worst-ever in-season debut for a new comedy series on NBC.

The 9 p.m. premiere of the Amanda Peet sitcom was followed by a 9:30 p.m. installment of “Bent” that fell even further, hitting a 0.9 average rating.

At the other end of the Wednesday ratings spectrum, the two-hour “American Idol” pulled a 4.9 average in 18-49 to give Fox an easy win for the night — even though that number was down by half a ratings point. Trailing Fox’s overall 4.9 for prime time were CBS (2.8 average), Univision (1.5), ABC (1.5 with mostly repeats) and NBC (1.0).

CBS saw “Criminal Minds” climb by four-tenths of a ratings point to a 3.2 average in 18-49, but “Survivor” was down three-tenths to a series-low 2.7 and “CSI” was off three-tenths to a season-low 2.5.
