Ramsay's Fox show
In terms of total viewership, the popular CBS comedy was No. 1, averaging 7.5 million people watching.
"Rookie Blue" started its season with a two-hour premiere that averaged 5.7 million viewers, down just 5% from its last kickoff in May 2013. But in 18-49, "Rookie" drew a 1.0, down 17% from last year's debut.
A couple things worth noting: The Season 4 premiere had a better lead-in with "Motive," instead of Thursday night's low-rated episode of "Black Box." Also, "Rookie Blue" had its biggest audience in more than a year, since the second episode of Season 4.
"Black Box" suffered in 18-49 from its move to the 8 p.m. time slot. It fell 13% to a low of 0.7 in the demo compared with its last original airing three weeks ago, but rose slightly in total viewership.
