From an article at dictionary.com today:
"The term CAPTCHA was first used by computer scientists at Carnegie Mellon University in 2000. CAPTCHA is actually an acronym that stands for Completely Automated Public Turing test to tell Computers and Humans Apart. That’s a pretty straight-forward title, except for the Turing test part. What exactly is a Turing test? Alan Turing was a computer theorist who invented the Turing test which humans use to see if a machine can converse like a human being. A CAPTCHA is actually an inverted Turing test whereby a machine tests to see if you are human or not, but the core principle remains."
My definiton of CAPTCHA = pain in the ass.
SPAMMERS = bigger pain in the ass.

I think someone mentioned it in another thread, but the CAPTCHA's you see on some sites, the ones with two words next to each other, are actually being used to help Google with their scanning of books. They know the answer to one of the words but they don't know what the second word is. They just show you what the image looks like and when enough people agree what the word is they accept the answer.
