The CW has picked up its first new series for next season, and it is not that new. After weeks of speculation, Supergirl will move from CBS to sister network the CW, which has renewed the superhero drama for a second season. The pickup, which comes hours after the most recent deadline for CBS to make a renewal decision on the freshman series, expands the CW DC superhero universe to four series, all from producer Greg Berlanti, as Supergirl is set to join The Flash, Arrow and DC’s Legends Of Tomorrow. One of them, Flash, already crossed over to Supergirl on CBS, making for a seamless integration of the newbie into the CW superhero squad.

A Supergirl move to the CW had been rumored for a while, with talks becoming real the last few days. A CW pickup was contingent on finding a way to produce a show of that scale (Supergirl commanded one of the highest license fees for a new series this season) for the CW. Producing studio Warner Bros TV already made a pre-emptive effort to trim costs with a planned move of production from Los Angeles to Vancouver in Season 2, which is now official. That will bring the show together with Berlanti’s current CW superhero drama series, which all are based in Vancouver.

The CW frequently had been mentioned as a suitable home for Supergirl because of the show’s young skew, the CW president Mark Pedowitz’s public comments about regretting not going after the project when it was originally pitched, and the fact that the CW is co-owned by CBS and Warner Bros.

This is the second time Supergirl had been rumored to move from CBS to the CW; it didn’t happen after the pilot last year. Previously, drama Ringer moved from CBS to the CW after the pilot.

Being based on a DC property, as it moves to the CW, Supergirl will remain solely owned by WBTV and not a co-production with CBS TV Studios as the original CW series automatically become.

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.

Based on the characters by DC Comics, Supergirl is executive produced by Berlanti, Ali Adler, Andrew Kreisberg and Sarah Schechter for Berlanti Productions in association with Warner Bros. TV. The series stars Melissa Benoist, Mehcad Brooks, Chyler Leigh, David Harewood, Jeremy Jordan and Calista Flockhart.
