The Thursday TV ratings for April 23rd are in; here are some of the highlights:

• The Big Bang Theory continues to dominate Thursday nights at 8 p.m. with a 3.5 rating in the key 18-49 demographic, and 14.40 million viewers on CBS, despite being down four tenths from last week.

• It also continues to help The Odd Couple stay afloat at 8:30 p.m., as it still holds a very respectable 2.0 rating and 9.47 million viewers.

• On ABC, Grey's Anatomy went up almost a full point to a 2.8 rating at 8 p.m., with 9.43 million viewers tuning in to see the departure of a main character. (Which was spoiled in advance; I'm tempted to think that helped the ratings rather than hurt them, though).

• 

  The rest of the 8 p.m. hour was not so hot, with Bones matching its series low 1.0 rating, and 4.56 million viewers, while CW's The Vampire Diaries was also down to a series low 0.6 rating and 1.39 million viewers.

• The Grey's bump didn't do much for Scandal at 9 p.m., though, which was down a tenth to a still timeslot-winning 2.3 rating and 7.77 million viewers on ABC.

• NBC's The Blacklist was down to a series low 1.4 and 7.23 million viewers at 9 p.m., while Fox's Backstrom stayed steady at a 0.8 rating and 3 million viewers.

• Elementary on CBS was down a tenth from last week, but still won the 10 p.m. timeslot with a 1.3 rating and 7.63 million viewers.

• Once again, NBC's Dateline and ABC's American Crime almost posted identical numbers at 10 p.m. Dateline edged the freshman drama out though with its 0.9 rating and 5.77 million viewers (American Crime notched a 0.9 rating and 4.14 million viewers).
