Today the CW announced the renewal of 8 of their shows. Among them are Arrow (Season 4), Reign (Season 3), Jane the Virgin (Season 2), The Flash (Season 2), The 100 (Season 3), Supernatural (Season 11), The Originals (Season 3), and The Vampire diaries (Season 7).
The CW president, Mark Pedowitz says that,
Each of these series have helped define what the CW is today, a network that is home to smart, provocative, quality programming, targeting a savvy adult audience. By picking up these shows now, our executive producers can start planning next season's story lines, and rolling these shows out throughout next season guarantees the CW will have more proven original series for our fall, mid season, and summer 2016 line-ups.
So which shows were not renewed? Hart of Dixie and beauty and the Beast. Pedowitz said that both were "not necessarily" cancelled, but the network wants to see how the rest of the season goes for the shows and if the ratings improve.
