Abstract: A content delivery system that uses a graphical user interface and host avatar to introduce users to and allow them to select from available content. A game delivery system that uses emulators to execute software written to run on a plurality of game platforms. The systems include a scalable, dynamic interface that launches and manages emulators in a manner that is largely transparent to the user, and a combination of linear and on-demand content provides users with a managed gaming experience not unlike that of interactive television.
