Watson's most obvious gaffe was its inability to recognize when an answer had already been given. One of two of the all-time Jeopardy! champions pitted against the super-machine, Ken Jennings, answered a question incorrectly with, "What is 1920s." Watson repeated the same answer. Steve Camepa, IBM's general manager of global media and the entertainment industry
explained that "Watson only takes his input from the question board so the fact that somebody else gave the same answer doesn't factor into what Watson says. He can't hear what the other players are saying, but maybe that's a feature we can add in the future."
