Once again, speaking as someone from a non North-American, non-English-speaking country: there are huge revenue opportunities out there for American TV networks!
Think about it. How do I get my Dollhouse? How did I get my Battlestar? Lost? Futurama? Right. Torrent. Why?
Because there’s no other way for people outside of North America to watch their favorite shows. I’d gladly pay one or two bucks to see my favorite shows every week online, when they come out. But the networks won’t let me. Their content is only available in North America. And that stinks. There’s millions to be made. It’s a global world. Get with it!
