Apparatus and methods are provided to implement a technique for providing supplemental information and interactive features for content, such as a movie. In one implementation, a content provider builds a package of information and interactive features (“interactive extras”) using a defined structure and API (application programming interface). The content provider gives the package of extras to several distributors (or provides access to some or all of the package through a network resource). Each distributor uses the package in the distributor's content distribution platform or system by conforming to the API for the package. In this way, the content provider can provide the same package of extras to multiple distributors that may have incompatible platforms without having to build custom packages for each platform. This allows the content provider to build the package once and also provides a more consistent experience across the distributor services.
