Pornography (from Greek πορνογραφια pornographia — literally writing about or drawings of harlots) (also informally referred to as "porn" or "porno") is the representation of the human body or human sexual behaviour with the goal of sexual arousal, similar to, but (according to some) distinct from, erotica.
Pornography may use any of a variety of media — written and spoken text, photos, sculpture, drawings, moving images (including animation), and sounds such as heavy breathing. Pornographic films combine moving images, spoken erotic text and/or other erotic sounds, while magazines often combine photos and written text. Novels and short stories provide written text, sometimes with illustrations. In addition to media, a live performance may also be called pornographic.
