TV Ratings: ‘Big Bang Theory’ finale, ‘Scandal’ lead Thursday

Fast National ratings for Thursday, May 7, 2015.

The latest series finale for “The Big Bang Theory” was down steeply from last year, but still ranked as Thursday's top show in all measures, leading CBS to overall victory. CBS could, however, only tie for the lead in the key demo as “Scandal” ruled its hour and gave ABC a share of the nightly crown.

After getting two weeks of inflation out of its latest death, ABC's “Grey's Anatomy” has settled back in around its series averages.

Meanwhile, a two-hour block of “Bones” recovered a bit from last week's dip below The Mulaney Line, while “Blacklist” was also up from last week.
