Deep Blue

Deep Blue is the world's most famous chess-playing computer. Deep Blue began as a chess program named Chiptest (later Deep Thought), created by students Feng-hsiung Hsu and Thomas Anantharaman at Carnegie Mellon University. The creators later joined the IBM corporation, which supported further development of the system. Deep Thought was eventually renamed Deep Blue, a twist on IBM's corporate nickname of Big Blue. Deep Blue lost a six-game match to world chess champion Garry Kasparov in 1996. But in the 1997 rematch, Deep Blue made history by defeating Kasparov 3.5 games to 2.5.
