On this day in 1933, the game of Monopoly is invented. Charles B. Darrow, of Germantown, Pa., showed his game to the executives of Parker Brothers, and they turned him down, because of 52 design errors. So, he sells 5,000 handmade sets to a Philly department store and they sell out. Unable to keep up with the demand for the game, he returns to Parker Brothers, and the rest is history. In it's first year, Monopoly was the best selling game in America!
