Rule 34
Rule 34 is an adage of internet culture positing that sexually explicit material exists for every conceivable subject, encapsulated in the phrase "If it exists, there is porn of it. No exceptions."[1] Originating from a 2003 webcomic by artist TangoStari (pseudonym of Peter Morley-Souter), the rule gained prominence as part of the broader "Rules of the Internet" compiled on imageboards like 4chan's /b/ board in the mid-2000s, reflecting the ubiquity of pornography across online spaces.[2] While often invoked humorously to highlight the exhaustive nature of erotic fan content and algorithmic content generation on platforms such as DeviantArt and Rule34.paheal.net, the principle underscores the scale of user-generated adult media, with dedicated archives cataloging millions of images and animations derived from mainstream media, video games, and historical figures.[3] Its defining characteristic lies in its empirical near-verifiability through search engines and niche communities, though exceptions persist for highly obscure or ethically restricted topics, challenging the absolute claim while affirming the rule's observational accuracy in most cases.[4]
