A pornographic actor/actress or a porn star is somebody who appears in pornographic movies, live sex shows or peep shows. Many actors and actresses may appear nude in films (usually filmed in explicit sexual genres). Most genres have specialists who achieve most of their recognition in a specific niche market such as bondage or strap-on sex.
The ability for people to view adult movies in the privacy of their own homes, owing to the popularity of the VCR (and now DVD) created a new adult market that could not be ignored. Additionally, the prevalence of the Internet has served as a catalyst for the sale of Internet pornography. The production values of adult films declined dramatically in the attempt to create new films for ever increasing demand. As a result of this, there are hundreds of adult film companies today, releasing tens of thousands of shot-on-video titles annually. As a result, there are thousands of people working as pornographic actors to meet the demand for these films.
