Showtime launches new 'Dexter' app

Includes social trivia game, previews, full episode downloads

On the heels of the fifth season premiere of "Dexter," Showtime has created a new app for the iPhone and iPod Touch.

In addition to previews for upcoming episodes, behind-the-scenes videos, interviews, schedule reminders and "Dexter: Early Cuts" webisodes, users can play a social trivia game where their "Dexter" knowledge is tested.

Full episodes can also be downloaded from iTunes via the app, along with podcasts and soundtracks.

HBO utilized social media while Season 3 of "True Blood" earlier aired this year, hosting live tweet sessions with special hosts and created a destination for fans to visit every Sunday.
