IBM Watson Defeats Jeopardy Champions On Television

In February 2011 IBM's Watson, a natural-language question-answering supercomputer, competed on Jeopardy! against champions Ken Jennings and Brad Rutter and won across the three televised episodes (Feb. 14–16). Watson finished with a game total of $77,147 and secured $500,000 for World Vision and World Community Grid; Jennings and Rutter received $150,000 and $100,000 respectively for charities. The match demonstrated early practical advances in conversational AI.
