Kasparov had previously defeated Deep Thought, the prototype for Deep Blue developed by IBM researchers in 1989, but he and other chess grandmasters had, on occasion, lost to computers in games that lasted an hour or less. An estimated 6 million people worldwide followed the action online.
Man was ultimately victorious over machine, however, as Kasparov bested Deep Blue in the match with three wins and two ties and took home the $400,000 prize. On February 10, 1996, after three hours, world chess champion Garry Kasparov loses the first game of a six-game match against Deep Blue, an IBM computer capable of evaluating 200 million moves per second.
