As the product requires less and less physical storage (IE: CD, DVD and etc.), We will see the Music and Movie industries attempting to charge us by the byte and not for the media that carries it. I can see why they are going after anyone who shares their product over the Internet as it's a medium and not their Intellectual Property.
Want to listen to the radio? That will be $xx.xx per minute. Your radio will report how long you've been listening and where you've been listening and what you've been listening to. How will you know what station to listen to? By each station allowing you to listen to them for a few minutes and "tease" you into listening to them for a fee.
The Internet is bringing on big changes in the way that we amuse ourselves. If we can put all of our entertainment choices on a mobile removable media device after directly downloading it from the net, how will the entertainment companies be able to charge us multiple times for it?
This is the endgame of all endgames. The entertainment industry has seen the future as far back as the introduction of MP3. You no longer have to go into a brick and mortar building to purchase a physical medium that holds their product while they hold the "copyright" to the product itself.
I can't wait for the proliferation of microphones in public places to catch you whistling a popular tune and charge you a royalty fee for it.
