Err...
This is (as mentioned above) all about media rights and how they are sold.
I spent some time working (in IT) for a TV rights company and I was a little shocked at how backward the issue of rights is....for instance hard media (such as DVD/Blu Ray) are sold separately to broadcast, but most rights in the early online days were sold with such wolly, open ended broad spectrum rights on long term deals and this has continued to be the case as it is the "status quo" so to speak....and almost all of these included localised deals for "online" :(
So rights for one particular program may be sold to a UK TV company with DVD, rebroadcast and in HD, but not SD...and to a French broadcast company with delayed cast, Blu Ray but not HD or DVD. It is frankly a total mess and there is a whole distribution market/workforce built up around this model that would resist any change for job preservation reasons.
Surely at some point the industry needs to accept that "online" is "online" and does not specify any legal or geographical domain. Global releases of media for film, TV, music and already to some point these days video games needs to happen as the glass walls of licensing are being smashed by pirating content that would otherwise be purchased legally.
