"Supergirl" heading to the CW was a move that most fans have anticipated after a few rumors. Many assumed that the reason why CBS decided to pass on its only comic property was because the show failed to reach the expected ratings; however, CBS President Glenn Geller clarified that the move was something both networks planned about, and if the deal with CW did not pan out, the network would still renew the show.
Geller spoke in front of the Television Critics Association (TCA) explaining the real reason behind the big move of "Supergirl" from CBS to the CW. Variety reported Geller clarifying that the move did not indicate that the show would have no chance for renewal if it remained in the original network, nor did it fail to reach the desired ratings. In fact, he revealed that the show averaged to over 10 million viewers per episode.
Geller further noted that "Supergirl" worked very well for the network, which is why the move was an opportunity to exploit on its success. He explained that since CBS co-owned CW, it would be a win-win for both networks' if the show would belong with its other superhero counterparts from the DC Extended Universe. He added that if the deal with CW did not pan out, CBS would renew the show for a second season.
The crossover episode of "Supergirl" with "The Flash" aired last March generated a boost in the shows' ratings. Comic Book Resources reported that with the show joining "The Flash," "Arrow," and "Legends of Tomorrow," there will be a lot of open windows with the storylines especially due to the anticipated crossovers between the four superhero multiverses.
