There Is a Porno About Everything, Except This
Harvard computational neuroscientist Ogi Ogas has started the first large-scale study about Internet porn and is examining the theory behind something called Rule 34, which basically boils down to: "If it exists, or can be imagined, there is Internet porn of it," the Washington Postreports.
Rule 34 was originally coined by Peter Morley-Souter who says he "accidentally created" it in 2005 after finding Calvin and Hobbes erotica and turned his astonishment that it existed into a web comic reading: "Rule 34. There is porn of it. No exceptions."
Ogas's study, which looked at over 55 million pornography searches in 2009 and 2010, found that there did in fact seem to be porn for everything, but the difference between what people searched for when they searched for porn and what they actually found was great. And with eight out of 10 of the largest tube sites being owned by the same company, MindGeek, that company has the power to control which sorts of porn they promote and which porn stays harder to find, which could be why you don't see wacky paper placemat kissing porn (or other similarly weird/obscure porn that I didn't just make up) taking over the world.
Ogas says that while he was studying Internet porn searches, he was surprised by how varied people's porn searches were, and how limited the results they'd actually get from the search were (which he says mostly boiled down to straight people having sort-of-wild-but-not-really straight sex).
Leonard Delaney, who has written Tetris erotica, told the Post that he thinks Rule 34 is accurate, but he also hasn't seen any porn made about Rule 34 itself, which is so clever I could cry.
Someone please make that porn.
