NBC Universal and Fox have signed deals with JumpTap to deliver ads on mobile devices, reports Adweek.

Ads will be targeted to users based on their behavior on JumpTap's search engine. They will appear on mobile-enabled sites for specific Fox shows and NBC corporate sites, including NBC Sports and Universal Pictures.

JumpTap powers the search functionality on devices from Virgin and Boost Mobile. It is also building its own publisher ad network to extend its ad sales reach.
