Supergirl has been renewed for a second season and is moving from CBS to its sibling-network The CW, according to The Hollywood Reporter. The show will join fellow DC superhero series The Flash, Arrow, and Legends of Tomorrow, with production moving from Los Angeles to Vancouver to cut costs. (The show was CBS's most expensive first-year show.)
The exact reasons for the move haven't been spelled out by CBS, but it's possible the network wants to double down on Supergirl's young audience. Although the show hasn't been the unmitigated success some were expecting, it ranked as the top new drama on CBS, pulling in plenty of younger viewers and attracting an average audience of 10 million across its 18-episode first season. The CW's audience is younger than CBS's, and although Supergirl might have launched on the latter in an attempt to pull in new viewers, it seems the experiment wasn't a total success. CBS's loss is The CW's gain.
