The other annoying thing is that "owning" something is getting to be non-existent anymore. Sure, I can "buy" all the seasons of Supernatural from iTunes. But I only "own" the show for was long as I have my iTunes subscription, and iTunes has the rights to show it, and I have internet service with enough bandwidth to stream it, and I'm not under a bandwidth cap or some other restriction.
Or I can grab a copy and it'll happily live on my hard drive forever, no need to worry about subscriptions or streaming rights or bandwidth limitations.
Tell me: in which of those scenarios do I actually "own" the series?
