Is SUPERGIRL Taking Flight To The CW?? Read the full article on AICN I am – Hercules!! Les Moonves, who has oversight of both CBS and The CW, is reportedly talking to “Supergirl” producer Warner Bros. about moving “Supergirl” from CBS to The CW. While “Supergirl’s” ratings are nowhere near as big as those of CBS hits like “Survivor,” “NCIS” and “The Big Bang Theory,” the Girl of Steel’s ratings remain comparable to those of The CW’s biggest hit, “The Flash.” Like the CW’s DC Comics series “The Flash,” “Arrow” and “Legends of Tomorrow,” “Supergirl” is produced by longtime “Dawson’s Creek” showrunner Greg Berlanti.
