Although Monopoly is frequently thought to have been invented by Clarence Darrow, its origins actually go back to 1904, when Lizie J. Magie patented a game called "The Landlord's Game". This original game was played in various forms over the years and later became known in some circles as "Monopoly." One version of the game with Atlantic City street names was taught to Clarence Darrow, who then took the game to Parker Brothers.
In recent years, the owners of the game have created dozens of version where the names of the properties and other elements of the game are replaced by others with some theme. There are version about [National Park]?s, Star Trek, Disney?, various particular cities (as Las Vegas), states, NASCAR, and many others.
