If a family wants to watch game of thrones today, every one can gather around one TV screen and watch it using one person's account.

I think Apple first needs to solve how to license a piece of media to one account that can be then be shared to anyone else in the same room, or a lot of families are never going to try it.

The Nintendo DS blew me away with its "buy one game and let others download the multiplayer part for free" approach.
