Starting January 11, the network is putting an extended preview across all official CW fan pages. The approach marks the first time that Facebook has hosted a screening across multiple pages, with “Unexpected” available to the network’s 5.4 million Facebook fans. The move allows CW to target its most dedicated viewers online.

The network is partnering with video provider Ustream for the effort. Fans who catch the “Unexpected” preview during the first 24 hours will be able to leave comments as they watch.

“Unexpected” is the story of a 15-year-old foster child who moves back in with her biological parents. The series debuts on the CW on Monday, January 18.
