Jump Technologies has hooked up with Fox to create an interactive mobile channel around the network's new series, Dollhouse, which debuts on February 13.

Dollhouse Interactive is a new channel within Jump's Nabbit service that lets mobile users "Nabb" content that interests them with the press of a button.

For the premiere episode, Nabbit users can access the interactive Dollhouse channel to answer a trivia question related to the episode. Viewers who answer correctly will have the chance to win an autographed wardrobe item.

Users who want to make sure they don't miss the episode can set up a text alert within Nabbit by texting "Dollhouse" to 878787 to receive a reminder on Friday afternoon.

Dollhouse, the latest offering from Buffy the Vampire Slayer creator Joss Whedon and starring Eliza Dushku, marks Nabbit's first interactive television deal. Prior to this, it focused on interactive radio.
