The CW started this season by expanding to six nights of prime-time programming for the first time since 2009. And as the season draws to a close, the network is looking at some other major changes: over a one-year period, the network will bid farewell to four of its signature shows: Supernatural, Arrow, Jane the Virgin and Crazy Ex-Girlfriend.
