In Sweden there was a period 1971-1980 when it was actually fully legal to produce and distribute “child porn” (but obviously not to commit the acts that sometimes occurred in certain pictures). In 1980 production and distribution became illegal. In 1995 the police were allowed to confiscate child porn although it was not a crime to possess. In 1999 possession became illegal. In 2011 it was criminalized to “watch” (without possessing) under certain circumstances. The definition of child pornography has also changed and widened enormously (and includes drawn images).
