It was a night of exits and lows on TV on Thursday. Last night’s one-hour live results show on American Idol (3.0/10) — which saw the first Top 10 finalist eliminated and a very short protest by judge Nicki Minaj because of it — was down 9% from last week’s final ratings results. It marked a series low for a regularly scheduled edition of Idol. The Fox singing competition wasn’t the only show to sink to new lows last night: Back with a new episode after three weeks, ABC’s Grey’s Anatomy took a 17% tumble to hit a series low. On NBC, Community (1.0/4) cratered 33% from last week’s show to hit its series low. And CBS’ Two And A Half Men (3.3/10) was down 15% form last week to hit a series low too.

CBS’ night was preempted in several markets due to ACC and SEC basketball tournaments, and ratings are likely to be adjusted in the final numbers more than usual. Back with a full-loaded Thursday lineup, the network kicked off as usual with The Big Bang Theory (4.5/15). The science geek sitcom had a rougher than usual ride, falling 18% to tie its season low. Person Of Interest (2.9/8) bopped up 4%, while a new Elementary (2.4/7) was flat with its last original February 21. With all that, CBS won the night in total viewers with 13.371 million watching and the adults 18-49 demographic.

A new Glee (2.0/6) followed Idol on Fox. After its 47% surge last week compared with its last February 14 original, Thursday night’s show fell 17%.

ABC kicked off the night with a Shark Tank (1.3/4) repeat, replacing the recently cancelled Zero Hour, and ended it with a Scandal (1.2/4) encore.

Back after three weeks, NBC’s Parks And Recreation (1.6/5) rose 14% over its February 21 original. Two months away from its series finale, The Office (1.9/5) was back Thursday and up 5% from its first original since Valentine’s Day. The struggling 1600 Penn (1.0/3) got a bit of good news: The freshman White House-based comedy was up 11% from last week’s season-low tie. The network also aired an encore of Law & Order: SVU (0.9/3) to end the night.

The CW had originals of The Vampire Diaries (1.1/4) and Beauty And The Beast (0.5/1). The former was down two tenths from its last original, while the latter was flat with its last new show.
