Man Vs. Machine on JEOPARDY

Machine decidedly beat man on the second round of Jeopardy's face-off with Watson the computer.

• Watson dominated most of the play, and was able to buzz in faster than human competitors Ken Jennings and Brad Rutter. The round ended with Watson holding $35,734, to Rutter's $10,400, and Jennings' $4,800.
• Watson showed weakness in Final Jeopardy. In the category "U.S. Cities," the clue was: "Its largest airport was named for a World War II hero; its second for a World War II battle." Ken and Brad both answered correctly with "Chicago," but IBM's supercomputer thought "Toronto" was a U.S. city.
