A backdoor pilot for a potential “Vampire Diaries” spin-off — titled “The Originals” —aired Thursday night, and less than a day later, CW placed an order for the show’s first season.

“As soon as we saw last night’s episode of ‘The Vampire Diaries,’ we knew we wanted more of ‘The Originals,’” CW president Mark Pedowitz said in a statement on Friday afternoon.

Joining the show on the network’s 2013-2014 schedule will be a third season of “Hart of Dixie,” starring Rachel Bilson as a city girl-turned small town doctor. Plus, a second season of freshman drama “Beauty and the Beast,” an update on the fairy tale — only this time the “beast” is a very attractive man with a small scar on his cheek.

These pick-ups are in addition to previously announced “Vampire Diaries” and “Arrow.” No word yet on “Nikita” or “Sex and the City” prequel “The Carrie Diaries.” The network already canceled ”Cult,” a midseason drama, halfway through its first season earlier this month.
