Mobile broadcast media Adston Cash is a mobile application that will allow users to participate in a free video quiz 12 times per day. At every contest period, users will view the commercial and then answer up to 10 questions regarding the content they were just exposed to, confirming what kind of a learning outcome took place. In return, we incentivize the videos by giving away prizes, one of which being cash. By disguising videos as contests, Adston Cash plans to use mobile devices to target the millions of users simultaneously.
