Quit making excuses and make it happen. The torrenters don't seem to have any trouble building a global distribution network, and they are hiding from the law while simultaneously kicking your butt.
If you don't want to make it happen, quit whining about losing money. I have money and you have TV shows, so let's make a deal.
Unfortunately, this arrangements prohibits them to use any alternate distribution channels to release the content on their own. Also, the regional company is unlikely to have any arrangements with services like Netflix and Hulu.
In the end its all about the money and bureaucracy.
The internet doesn't really know regions, so local distribution partners are no longer a concern (Except maybo for localizing content).
Distribution of content globally via Internet would still require regional monetization effort like regional advertisers and payment processing.
What do you do in the case where a show is shown on ABC in the US and Channel 4 in the UK, and they both have online streaming? How do you just make that happen? Who is going to give up their rights to broadcast online? Are you just going to wish the contracts away? Yes, the torrenters have no problem avoiding the legal limits because they are illegal, that's not an answer.
(Okay, I'll answer.)
Make a new territory called "Internet" which charges viewers directly. If a UK broadcaster wants the UK rights, that would still be available separately. People who would pay a premium aren't really in the same market as people who watch free-with-ads channels.
I know channel 4 etc won't like having a competitor with the same shows on their turf, but they do already - torrenters. At least this way, the competitor will just be one that charges a premium that will only be used by big fans of a show. The casual viewer will remain with the free-with-ads channel.
