One day back in 2003, Ken Jennings and his college buddy Earl did what hundreds of thousands of people had done before: they auditioned for Jeopardy! Two years, 75 games, 2,642 correct answers, and over $2.5 million in winnings later, Ken Jennings emerged as trivia’s undisputed king. Brainiac traces his rise from anonymous computer programmer to nerd folk icon. But along the way, it also explores his newly conquered kingdom: the world of trivia itself.Jennings had always been minutiae-mad, poring over almanacs and TV Guide listings at an age when most kids are still watching Elmo and putting beans up their nose. But trivia, he has found, is centuries older than his childhood obsession with it. Whisking us from the coffeehouses of seventeenth-century London to the Internet age, Jennings chronicles the ups and downs of the trivia fad: the quiz book explosion of the Jazz Age; the rise, fall, and rise again of TV quiz shows; the nostalgic campus trivia of the 1960s; and the 1980s, when Trivial Pursuit® again made it fashionable to be a know-it-all.
