Once, Norway, Sweden and Denmark had its own tv channel. TV3 was fully Scandinavian from 1989 until 1992, when it split.
Here is a very special Christmas show that was broadcasted on TV3 in 1989 with characters talking in Swedish and Norwegian. They also mention things in Danish.
This must be the best Christmas advent show ever made I think. I remember this so much more than the other advent calendar shows. It was made in co-operation with Disney and it became an icon of how well the Scandinavian version of TV3 was.
