Thursday Ratings: ‘Wayward Pines,’ ‘Aquarius,’ ‘Dome’ drop pre-holiday

Fast National ratings for Thursday, July 2, 2015.

“Big Brother” dominated the 9 p.m. hour on Thursday night and helped carry CBS to easy victories in all measures on a sluggish pre-holiday evening.

With overall usage levels down by eight percent on the Thursday leading into the July 4 holiday weekend, most of primetime's originals were down, including drops for “Wayward Pines,” “Aquarius,” “Under the Dome,” “Mistresses” and “Astronaut Wives Club.”

“Hannibal” and “Rookie Blue” were among the few shows to stay flat week-to-week, though that was mostly a factor of how low both returning dramas had been in the previous week.

Let's get to the numbers…

Among adults 18-49, CBS averaged a 1.3 rating for Thursday night, easily ruling in the key demographic. FOX was second with a 0.8 key demo rating, followed closely by the 0.7 key demo rating for ABC. NBC's 0.5 key demo rating and the 0.2 key demo rating for The CW trailed.
