Production of erotic films commenced almost immediately after the invention of the motion picture.
Two of the earliest pioneers were Frenchmen Eugène Pirou and Albert Kirchner.
The rise of the Internet in the late 1990s and early 2000s similarly changed the way pornographic films were distributed and furthermore, complicating the censorship regimes around the world and the legal prosecution of obscenity.
Pornographic films are typically categorized as either softcore or hardcore pornography.

Subgenres can also be classified into the characteristics of the performers or the type of sexual activity on which it concentrates and not necessarily on the market to which each subgenre appeals.
The subgenres usually conform to certain conventions, and each may appeal to a particular audience.
Kirchner (under the name "Léar") directed the earliest surviving erotic film for Pirou.
The 7-minute 1896 film Le Coucher de la Mariée had Louise Willy performing a bathroom striptease.
