$300 million lawsuit

In October 1984, Fred L. Worth, author of The Trivia Encyclopedia, Super Trivia, and Super Trivia II, filed a $300 million lawsuit against the distributors of Trivial Pursuit. He claimed that more than a quarter of the questions in the game's Genus Edition had been taken from his books, even to the point of reproducing typographical errors and deliberately placed misinformation. One of the questions in Trivial Pursuit was "What was Columbo's first name?" with the answer "Philip". That information had been fabricated to catch anyone who might try to violate his copyright.
