The board game Monopoly has its origin in the early 20th century. The earliest known version, known as The Landlord's Game, was designed by Elizabeth Magie and first patented in 1904, but existed as early as 1902.[1][2][3] Magie, a follower of Henry George, originally intended The Landlord's Game to illustrate the economic consequences of Ricardo's Law of economic rent and the Georgist concepts of economic privilege and land value taxation.[4] A series of board games was developed from 1906 through the 1930s that involved the buying and selling of land and the development of that land. By 1933, a board game already existed much like the modern version of Monopoly that has been sold by Parker Brothers and related companies through the rest of the 20th century, and into the 21st. Several people, mostly in the midwestern United States and near the East Coast of the United States, contributed to its design and evolution.
By the 1970s, the false idea that the game had been created by Charles Darrow had become widely believed; it was printed in the game's instructions for many years,[5] in a 1974 book devoted to Monopoly,[6] and was cited in a general book about toys as recently as 2007.[7][8] Even a guide to family games published for Reader's Digest in 2003 gave credit only to Darrow and none to Elizabeth Magie or any other contributors, erroneously stating that Magie's original game was created in the 19th century and not acknowledging any of the game's development between Magie's creation of the game and the eventual publication by Parker Brothers.[9]
Also in the 1970s, Professor Ralph Anspach, who had himself published a board game intended to illustrate the principles of both monopolies and trust busting, fought Parker Brothers and its then parent company, General Mills, over the copyright and trademarks of the Monopoly board game. Through the research of Anspach and others, much of the early history of the game was "rediscovered" and entered into official United States court records. Because of the lengthy court process, including appeals, the legal status of Parker Brothers' copyright and trademarks on the game was not settled until 1985. The game's name remains a registered trademark of Parker Brothers, as do its specific design elements; other elements of the game are still protected under copyright law. At the conclusion of the court case, the game's logo and graphic design elements became part of a larger Monopoly brand, licensed by Parker Brothers' parent companies onto a variety of items through the present day. Despite the "rediscovery" of the board game's early history in the 1970s and 1980s, and several books and journal articles on the subject, Hasbro (which became Parker Brothers' parent company) did not acknowledge any of the game's history prior to Charles Darrow's involvement on its official Monopoly website as recently as June 2012,[10] nor did they acknowledge anyone other than Darrow in materials published or sponsored by them, at least as recently as 2009.[11]
International tournaments, first held in the early 1970s, continue to the present, although no national tournaments or world championships have been held since 2015. Starting in 1985, a new generation of spin-off board games and card games appeared on both sides of the Atlantic Ocean. In 1989, the first of many video game and computer game editions was published. Since 1994,[12] many official variants of the game, based on locations other than Atlantic City, New Jersey (the official setting for the North American version) or London, have been published by Hasbro or its licensees. In 2008, Hasbro permanently changed the color scheme and some of the gameplay of the standard US Edition of the game to match the UK Edition, although the US standard edition maintains the Atlantic City property names.[13] Hasbro also modified the official logo to give the "Mr. Monopoly" character a 3-D computer-generated look, which has since been adopted by licensees USAopoly (The OP), Winning Moves and Winning Solutions. And Hasbro has also been including the Speed Die, introduced in 2006's Monopoly: The Mega Edition by Winning Moves Games, in versions produced directly by Hasbro (such as the 2009 Championship Edition).[14][15]
