The CW announced today that it has renewed iZombie and The Originals for next year as the CW is the first network to finish its decisions on all its shows. 11 will be coming back while No Tomorrow and Frequency were cancelled, The Vampire Diaries has ended, and Reign is going to end.
Both iZombie and The Originals were held for midseason this year but have performed decently, especially The Originals on Friday nights. With two veteran shows ending, it's not surprising that the CW is giving these two shows more life. The Originals getting renewed keeps the universe of The Vampire Diaries alive, at least for now.
