I think the future of multimedia is going to be internet distribution, either ad supported (such as when you watch a TV episode on nbc.com or southparkstudios.com) or outright purchasing such as itunes. The cost of bandwidth is dropping so rapidly that the cost of streaming content to users can easily be covered by a commercial every 10 minutes or so. You can already see this cutting into traditional dvd sales with netflix renting movies directly to game systems.
