BrightSpot.tv is a new advertising model that provides users with discounted (or free) subscriptions to content providers like Napster, MLB TV and Gamefly. The one stipulation is that they have to watch commercials on their site. BrightSpot.tv has viewers watch and interact with advertisers so they can build up their ad-watching credit to apply to subscriptions. For instance, you have to watch $15 worth of commercials to get $15 off on your monthly Napster subscription. You can guess that this is aimed at a younger demographic who have limited budgets and time to spend on watching commercials.
BrightSpot.tv has received funding from MLB and NBA owners Jerry Colangelo (Phoenix Suns, Arizona Diamondbacks) and Jerry Reinsdorf (Chicago White Sox, Chicago Bulls). This probably explains the connection with MLB and NBA content providers.
Other new advertising models include SpiralFrog.
