TV Ratings: ‘Grey’s Anatomy’ grief, low ‘Big Bang Theory’ lead Thursday

Fast National ratings for Thursday, April 30, 2015.

Two hours of “Grey's Anatomy” grieving helped ABC eke out a slim Thursday win among young viewers, while an unusually low-rated “The Big Bang Theory” helped pace CBS' comfortable overall victory. 

“Grey's Anatomy” was down from last week's poorly-kept-secret of a shocker, but it was still the show's second best performance since January.

Thursday was full of ugly numbers, including a series low for “The Blacklist,” a dip below The Mulaney Line for “Bones,” a low finale for “Backstrom” and an inability to retain a solid lead-in from “American Crime.” 

On the more positive side, “Mom” ended its season on a high-ish note.

Let's get to the numbers…

Among adults 18-49, ABC averaged a 2.0 rating for Thursday night, edging out CBS' 1.9 rating in the key demographic. [With “Big Bang Theory” prone to Live+SD Finals upticks, it wouldn't be surprising to see CBS either tie or top ABC for the night.] There was a big drop to NBC's 0.9 key demo rating and to the 0.8 key demo rating for FOX. The CW averaged a 0.4 key demo rating for the night.

Overall, though, CBS averaged an estimated 8.85 million viewers and a 5.5 rating/10 share for primetime, topping ABC's 4.8/8 and 7.04 million viewers. Again there was a big gap to third place with NBC averaged 4.895 million viewers and a 3.2/6, followed by FOX's 3.51 million viewers and 2.3/4. The CW averaged 1.04 million viewers and a 0.7/1 for the night.
