Master of Memes

Like a lot of unsanitary places, 4chan is gloriously fertile. What grows there is memes—ideas and jokes and fads that spread across the Net. Here's an example: there used to be a tradition on 4chan that every Saturday people would post pictures of cats. It was called Caturday. People added captions representing what the cat would say if cats could talk. One day somebody posted a shot of a fat gray cat looking at the camera and saying, "I CAN HAS CHEEZBURGER?"

Somehow that picture escaped 4chan onto the wider Web. Without knowing where it came from, somebody saw it and liked it enough to start a blog about it: icanhascheezburger.com. Soon other people were making their own Caturday-style pictures and calling them "lolcats." Now you can buy lolcat T shirts and lolcat buttons and lolcat fridge magnets. Last September investors bought icanhascheezburger.com for about $2 million.
