Arrow has been The CW’s best series premiere since 2009 and currently stands as the network’s most watched show (4.3 million).
The CW has also renewed The Vampire Diaries for a fifth season and ninth for Supernatural.
“We said last year that one of our goals was to establish building blocks to grow on, and now with our new hit Arrow and fan favourite Supernatural on Wednesday night, and the continued success of The Vampire Diaries on Thursday, we’ve been able to do that,” said CW president Mark Pedowitz.
“Not only do Arrow, Supernatural and The Vampire Diaries perform well on-air, they’re also extremely successful for us both digitally and socially.”
But 90210, Nikita, Hart Of Dixie, The Carrie Diaries and Beauty And The Beast with Jay Ryan face less-certain futures.
