Porn is the portrayal of explicit sexual subject matter for the purposes of sexual excitement and erotic satisfaction. 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.

A pornographic actor or porn star performs in pornographic films. In cases where limited dramatic skills are involved, a performer in pornographic films may be called a pornographic model.

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. As well as the porn industry, there is a large amount of non-commercial pornography. This should be distinguished from commercial pornography falsely marketed as featuring "amateurs." The Alt Sex Stories Text Repository focuses on prose stories collected from Usenet. Various Usenet groups are focused on non-commercial pornographic photographs.
