CNBC’s new prime-time entertainment block — CNBC Prime — received mixed ratings in its debut, reports TVNewser.com.

The cable channel on Tuesday rolled out the CNBC Prime block’s first two shows, the antiques search "Treasure Detectives" and the car-flipping show "The Car Chasers." “Treasure” drew 279,000 total viewers at 9 p.m., while “Chasers” attracted 210,000 viewers at 10 p.m.

That means "Treasure Detectives" improved significantly on the previous week, when an episode of "60 Minutes on CNBC" drew 195,000 viewers in the time slot.

"Car Chasers," though, but was down substantially from last week, when "American Greed" drew 281,000 viewers. "American Greed" is the second-most-popular show on the channel in total viewers.

"In other words, both CNBC Prime programs will likely be among CNBC’s highest-rated when all is said and done, even though one of them is down from the week prior," the story notes.
