Crackle, a free service, has a somewhat limited and eccentric selection of movies and television shows to choose from, although they do have a rather impressive selection of classic anime like Ah! My Goddess and Galaxy Express 999.
Best Buy's CinemaNow ecosystem has more new releases to choose from, but its services require cash money. It's unclear whether all of the content on these two services will be available through the respective apps, or if some content will be restricted, like the YouTube and Hulu Plus apps. If our calculations are correct, Xbox Live only needs 2 more movie apps and 4 more internet radio apps before it becomes self aware.
