According to About.com, Trivial Pursuit was created in 1979 by Chris Haney and Scott Abbott, two Canadian journalists. While playing a game of "Scrabble," the pair found some of the game's tiles were missing and decided to create their own game instead. They spent the next few years developing "Trivial Pursuit," which was officially released in 1982. Although early copies of the game were sold at a loss, it quickly grew in popularity, going on to sell millions of copies.
