Various groups within society have considered depictions of a sexual nature immoral, addictive, and noxious, labeling them pornographic, and attempting to have them suppressed under obscenity and other laws, with varying degrees of success.
Such works have also often been subject to censorship and other legal restraints to publication, display, or possession, leading in many cases to their loss.
Pornography may be presented in a variety of media, including books, magazines, postcards, photographs, sculpture, drawing, painting, animation, sound recording, phone calls, writing, 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.
After the modern invention of photography, the photographic pornography was also born.The primary subjects of present-day pornographic depictions are pornographic models, who pose for still photographs, and pornographic actors or "porn stars", who perform in pornographic films.If dramatic skills are not involved, a performer in pornographic media may also be called a model.Those that were made were produced illicitly by amateurs starting in the 1920s, primarily in France and the United States.Processing the film was risky as was their distribution. In 1969, Denmark became the first country to abolish censorship, thereby decriminalizing pornography, which led to an explosion in investment and of commercially produced pornography.
