One of the headlines of this upfront was the move of Supergirl from CBS to the CW, which is co-owned by CBS and Warner Bros., the studio that produces the superhero drama.

Before CBS’ press breakfast, I asked CBS Corp. boss Leslie Moonves about the decision to move the show. “It’s great to own two networks,” he said. “Supergirl fits better on the CW.”

CBS LogoMoonves praised CBS’ partnership with Warner Bros. and his relationship with CEO Kevin Tsujihara. He said that talks about Supergirl went on for a month before the agreement for the show’s relocation to the CW was made.

“If they didn’t go there, we would’ve probably taken it back,” Moonves said.

CBS Entertainment president Glenn Geller shared similar sentiment during CBS’ morning press briefing. “It’s a win-win since we co-own the CW,” he said. “We worked out great deal. And who would say we wouldn’t have picked it up had it not gone to the CW.”

Despite the fact that its numbers tapered off significantly after a strong start, Supergirl, aided by a solid DVR play, averaged a 2.4 rating among adults 18-49 in a competitive time slot, ranking as the No. 1 new CBS drama and No. 4 new network series overall (behind only Blindspot, Life In Pieces and Quantico) in the demo this season. It is CBS’ youngest-skewing new drama and averaged nearly 10 million viewers.
