Pornography
In the nations of Western Europe and the United States, the law permits people who have reached the legal age of adulthood (the age of majority) to own, buy, sell, make, or participate in pornography.  Laws about the public display of pornographic materials for sale may vary in the West: in The Netherlands the very liberal laws allow stores that sell pornography to display books, magazines, photographs, and the covers of videos openly, but in Canada and the United States the laws require that such stores keep pornographic material out of the sight of children. In some parts of Asia (Indonesia, Iran and Pakistan) making or owning pornography is a crime.
