On this day in 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.
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.
