Pornography (often abbreviated to 'porn' in informal usage) is the explicit portrayal of sexual subject matter. Pornography may use a variety of media, including books, magazines, postcards, photos, sculpture, drawing, painting, animation, sound recording, film, video, and video games. The term applies to the depiction of the act rather than the act itself, and so does not include live exhibitions like sex shows and striptease. A pornographic model poses for still photographs. A pornographic actor or porn star performs in pornographic films. If dramatic skills are not involved, a performer in porn films may be also be called a model. Pornography is often distinguished from erotica, which consists in the portrayal of sexuality with high-art aspirations, focusing also on feelings and emotions, while pornography involves the depiction of acts in a sensational manner, with the entire focus on the physical act, so as to arouse quick intense reactions.
