I'm suggesting that if you add eg "Miramax" to your library by paying their subscription you gain access to their back catalogue. I may only want one or two movies from them, but thanks to the bundling I have access to way more. Or Disney might divide subscriptions up by its studios or labels. I don't see them offering individual shows in a subscription, as that has limited appeal (has been done already and doesn't _really_ require its own platform)

Overall, it's not so different from cable channels, except that it's on-demand.
