I actually can't think of any digital market that ISN'T region-locked anymore. It's ridiculous that you can buy physical items and have them delivered across oceans but online distributors refuse to send you bits if your IP address is in the wrong range.
Is that the case, or is it the legal arms of media industries not ALLOWING distribution except under very specific circumstances? Maybe that's what you're saying here, but it seems like your trying to blame those to distribute, rather than onerous restrictions placed upon them by others.
