Three weeks into its freshman run, CBS‘ new sci-fi drama series Extant is sliding an hour from the post-Big Brother 9 PM berth to 10 PM starting this Wednesday. The Halle Berry-starrer, which has been sliding in Live+Same Day viewing since the premiere, most recently logging a 1.1 in 18-49, will switch places with the Criminal Minds repeats that had been airing at 10 PM.

CBS is making the change after a similar switcheroo worked well on Sunday. There, new drama Reckless too was falling hard in the ratings at 9 PM, behind Big Brother, leading to returning Unforgettable at 10 PM. After CBS switched Unforgettable and Reckless, Unforgettable‘s numbers naturally went up (+43% in 18-49) with a stronger lead-in from Big Brother. But Reckless didn’t suffer any further drop among adults 18-49 in its transition to 10 PM, staying consistent in the demo and even picking up 5% in viewers. CBS is hoping for a similar outcome on Wednesday, with an established drama lead-in from a stronger, Big Brother-buoyed Criminal Minds stabilizing Extant.

The scheduling change is made with enough lead time for this Wednesday’s DVR listings to be updated, which is important for Extant. The series debut of the mystery drama has seen a 50% bump in 18-49 from Live+SD to Live+7.
