Developing fantasy sports apps just got a bit easier thanks to CBS Sports. An early player in the space, they are opening up their service and APIs to third party developers and companies to build free and paid co-produced products and services. So far, Sports Media, Bloomberg Sports, Rotowire, StatSheet, Major League Baseball Advanced Media, and Ziguana have all signed on to create apps, which will be available in the app store launching this month.
