What is Rule 34?

Rule 34 is an internet adage stating 'If it exists, there is porn of it.' This principle drives the massive production of fan-made adult content featuring characters from all media — games, anime, movies, cartoons, and more. Rule 34 content is hosted across dedicated sites like rule34.xxx and rule34video.com. The rule has proven remarkably accurate, with adult fan art appearing for virtually every fictional character.
