This morning CBS is holding their 2015-2016 Upfronts and announcing their fall TV schedule. Thanks to THR, we have some information about Supergirl. CBS has put the new Warner Bros. TV produced show on Mondays at 8 p.m. ET. That’s right, in the same time slot as Fox’s hit series, Gotham. Though Supergirl isn’t scheduled to premiere until November, which is when Gotham will more than likely start taking a midseason break, or very close to it.
