Why are cookies named cookies anyway?
Cookies do seem a rather odd name for something used for computers. But, the answer is actually quite simple. Years ago, sometime in the '70s, Xerox made a computer system that made use of quite a novel idea. It saved some of the data about the user who was logged in on the client side rather than the server side. This was pretty darn new for the time.
The data was saved in a small file called a "cookie". In fact, these files were held within a place on the machine called a "cookie jar". Now, the reason Xerox took the name cookie for their invention is somewhat clouded in legend, but here is the one telling that seems most reasonable:
It seems that hackers at that time really were into "The Andy Williams Show". On this show was a character called the "Cookie Bear", played by Janos Prohaska. He would follow Andy about and ask for a cookie only to be rebuffed by Andy saying "No cookie, not now, not ever!". In honor of Cookie Bear the Xerox programmers decided to call the little file a cookie.
Since this character appeared on the show during the early '70s that would seem to be some evidence (ok weak but...) that this is the true origin rather than the cookie monster on Sesame Street as some have suggested. Especially since Cookie Monster of Sesame Street fame allegedly is named after the aforementioned Cookie Bear making "Cookie Monster" the origin a retcon or retroactive continuity.
