запрет порно, есличо, действовал на протяжении 20 лет
(1986-2005), соответствующий закон никто не отменял,
просто ограничили его область применимости

зоопорно, порно с насилием, некро, бдсм/рейп/насилие,
вот это все так и не легализовали

Norway

Hardcore material was for a long time illegal de jure, but
legal in practice, that is, illegal to produce, distribute
and sell, but legal to possess. One could e.g. acquire it
abroad, on the internet, or via satellite TV. There were
also some illegal porn shops, especially in the larger
cities. To satisfy legal requirements, editors of erotic
magazines, domestic TV channels and cable TV obscured
sexual organs in activity using black rectangles
etc. After the Supreme Court on 7 December 2005
unanimously acquitted a former magazine editor for
publishing unobscured hardcore pornography in 2002,
however, it is understood that printed hardcore
pornography is no longer illegal, and pornographic
magazines and movies were introduced in general stores
from 2006. Public TV as well as cable TV seems to stay
with the old rules, and is not yet clear if the Supreme
Court decision will affect TV. (NB: The depiction of
illegal sexual activities, such as those involving
children, animals, necrophilia, rape, violence or the use
of force, remains illegal.) [8][9][10]
