Ratings: Rookie Blue Dips, Big Brother and Hope Slip, Fox News Draws Biggest Crowd

Big Brother drew 5.5 million total viewers while scoring a 1.9 demo rating this Thursday night, marking week-to-week declines of 13 and 17 percent.

That said, BB netted the best demo number on any dial for the night, while Fox News Channel’s coverage of the Republican National Convention was Thursday’s most watched program, with 9.1 million viewers.

Like its time slot rival Big Brother, NBC’s Saving Hope (2.54 mil/0.5) saw week-to-week declines, of 11 and 17 percent, while Rookie Blue (3.8 mil/0/9) — airing an hour earlier this week — dipped just 10 percent.

Reminder: Saving Hope‘s final two episodes of Season 1 will air on Saturdays — on Sept. 8 and 15.

Earlier in the evening, ABC’s just-renewed Wipeout (3.5 mil/1.1) registered drops of 27 and 15 percent.

The CW’s The Next was the night’s steadiest program, shedding just a few (of its few) eyeballs (total audience: 770,000 viewers) and matching its week-ago demo (0.3).
