Thanks! Wasn't aware of the Archive link. Even so, it is hit and miss with what's available.
For example, the most popular show I've heard of, Skram[1], requires a login -- but Storst av alt (another I've heard of) does not.
"Skam" is a bit different because even though it's produced by NRK it got so popular elsewhere that NRK is licensing it to other countries. So they aren't free to just dump it freely worldwide.
I think often fiction-type shows like Vikingane has complicated licensing as it is normally produced by some sort of third-party, but other programs like news and the mintioned gameshow is produced in-house and NRK has all the rights. There is a very nice page with an archive of old programs [2], I think most of this should be globally available.
I of course agree in general that geo-restrictions and localized distribution rights are stupid concepts.
