What is XXX ?
"XXX" is the common definition for highly pornographic materials.
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.
With the emergence of social attitudes more tolerant of sexuality and with more explicit definitions of obscenity in law, an industry for the production and consumption of pornography arose in the latter half of the 20th century. The introduction of home video and the Internet saw booms in a porn industry that today generates billions of dollars a year worldwide
