From plinko.net we learn that
HTTP status codes were established by the World Wide Web Consortium (W3C) in 1992, as a part of the HTTP 0.9 spec. They were defined by Tim Berners-Lee, the same person who single-handedly invented the web and the first web browser in 1990. We at the 404 Research Lab like to think of him as The Man Who Made All Of This Possible.
But history means nothing to me! 404 has dominion over all but this feeble blog! A thorough takeover!
