Historically Changes Of Pornography

Pornography or porn is the depiction of explicit sexual subject matter for the purposes of sexual excitement.

Pornography may use any of a variety of media, ranging from books, magazines, postcards, photos, sculpture, drawing, painting, animation, sound recording, film, video, or video game. However, when sexual acts are performed for a live audience, by definition it is not pornography, as the term applies to the depiction of the act, rather than the act itself. Thus, portrayals such as sex shows and striptease are not classified as pornography.

Pornography has often been subject to censorship and legal restraints on publication on grounds of obscenity. Such grounds and the very definition of what is or is not pornography have differed in different historical, cultural and national contexts.
