Milestones along the way in Watson's colorful history

How did IBM's Watson get to where it is today? Here are some key events that happened along the way. IBM's Deep Blue computer beats world chess champion Garry Kasparov in a six-game match that lasts several days and receives massive media coverage around the world. It also inspires researchers at IBM to undertake an even bigger challenge: build a computer that could beat the champions at Jeopardy. Watson competes on Jeopardy and defeats the TV quiz show's two biggest all-time champions.
