TV Ratings: Bubble Shows 'Black Box' and 'Bad Teacher' Drop

The only two Thursday series with uncertain fates ahead of upfronts both take tiny hits, while NBC's American Comedy Awards makes a soft landing.
"Bad Teacher"

The Big Bang Theory posted a season low on Thursday night, shedding eight-tenths of a point for a 3.7 rating with adults 18-49. That big drop didn't hurt The Millers (2.0 adults) or Two and a Half Men (2.1 adults), each of which were even with the last week's outing.

Bad Teacher, which has yet to score a renewal, was off a tenth of a point with a 1.3 rating while Elementary (1.5 adults) was down by the same measure. CBS scored a dominant 2.0 adults rating and 8.8 million viewers for the night.

Hell's Kitchen (1.5 adults) was steady with a one-tenth drop, while American Idol (1.6 adults) improved by a tenth. Canceled Surviving Jack (1.2 adults) posted two-tenths of poorly timed growth, giving Fox nightly averages of a 1.5 rating and 4.9 million viewers.

Grey's Anatomy (2.3 adults) dropped three-tenths of a point from last week's lift. Black Box (1.1 adults) dropped another two-tenths of a point, making a pickup look even more unlikely. ABC netted an average 1.3 rating with adults 18-49 and 4.9 million viewers.

NBC played an even Hollywood Game Night (0.9 adults) in a special hour, leading in to a lackluster debut for the American Comedy Awards (1.0 adults). NBC averaged a 1.0 rating in the key demo and 3.2 million viewers.

Both The Vampire Diaries (0.7 adults) and Reign (0.5 adults) held steady on The CW.
