I too can easily remember a time when we had two TV channels, one Norwegian and one Swedish.
I remember the coming of the Scandinavian channel TV3 (which started out the same for the 3 Scandinavian countries, but ended up with one for each after some years). I remember MaxSat, their kids' show hosted by one Norwegian girl and two boys (Danish and Swedish), and how at the end of the day's schedule, they'd play snippets of all 3 national anthems. I always liked watching that.
I remember well when we got our next 2 Norwegian channels, TVN and TV2.
