Pornographic video

Pornographic films, or sex films, are films that present sexually subject matter for the purpose of sexual arousal and erotic satisfaction of the viewer. Pornographic films present sexual fantasies and usually include erotically stimulating material such as nudity and depictions of sexual intercourse. A distinction is sometimes made between "erotic" films and "pornographic" films on the basis that the latter contain more explicit sexuality, and focus more on arousal than storytelling, but the distinction is highly subjective.

Pornographic films are produced and distributed on a variety of media, depending on demand and the technology available, including traditional film stock in various formats, video for home viewing, DVDs, Internet download, cable TV and other media. Today, pornographic films can be sold or rented on DVD, shown through Internet streaming and special channels and pay-per-view on cable and satellite, and in rapidly disappearing adult theaters. They are generally not permitted to be shown in mainstream cinemas or on free-to-air television. Films with risqué content have been produced since the invention of the motion picture in the 1880s. Production of such films was profitable, and a number of producers began to specialise in their production. However, various groups within society considered such depictions immoral, labelling them pornographic, and attempting to have them suppressed under obscenity laws, with varying degrees of success. Such films continued to be produced but could only be distributed by underground channels. Because the viewing of such films carried a social stigma, they were viewed at brothels, adult movie theaters, stag parties, at home, in private clubs and also at night cinemas. Only in the 1970s, during the Golden Age of Porn, were pornographic films semi-legitimized; and by the 1980s, pornography on home video achieved wider distribution. The rise of the Internet in the late 1990s and early 2000s similarly changed the way pornographic films were distributed and furthermore, complicated the censorship regimes around the world and the legal prosecution of obscenity.
