The lesser-known (and, in Canada, harder to access) fifth network continues to cater to a younger demographic; less programmed hours and lower ratings expectations allow marginal shows to stick around longer than they might on another net. Renewed: Arrow, Supernatural, The Vampire Diaries, Reign, Hart of Dixie, The Originals, The 100. Cancelled: Nikita (series ended), The Tomorrow People, The Carrie Diaries, StarCrossed. Likely to survive: Most renewals have already been issued. On the bubble: Beauty and The Beast, Whose Line Is It Anyway?
