I think the point is market segmentation and ancient distribution channels/agreements are holding them back. This is why things like Hulu end up being US-only. Why they can't get this stuff right even within the same market? Well for one, they are struggling even with what they have. E.g. a number of episodes of The Big Bang Theory would crash the browser at the third (final) commercial segment consistently (even after restarting the browser and attempting to skip to the that commercial segment). They can't even get the tech to do the limited amount that they do now right.
So what is needed is a world wide network that can automatically insert relevant regional/local ads into popular shows so that they can be streamed online with no region restrictions.
Sounds like a good startup idea for a seasoned founder, since they're more likely to get 'color' levels of funding required to do this at scale from the get go. As unfortunately I don't see this kind of startup getting traction in a limited market, hence go big or go home levles of funding.
