31st December 1935: Monopoly board game patented
As early as 1902 an Illinois-born writer and engineer called Elizabeth Magie created a board game called The Landlord’s Game which bears striking similarities to Monopoly. She patented this game in 1904 and approached Parker Brothers with the idea in around 1910. Although they declined to publish it, her self-produced copies became popular with Quakers, university students, and members of the public who supported Georgist economics.
Magie, by now married and with the new name Phillips, re-patented an updated version in 1924 and was again turned down by Parker Brothers. However, the updated version spread widely through word-of-mouth, with Charles Darrow’s wife eventually learning it. Darrow began to distribute his own version of the game, and in October 1934 was himself rejected by Parker Brothers who found the game “too complicated, too technical, [and] took too long to play.” However, successful Christmas sales led Parker Brothers to reverse their decision and the game from Darrow in March 1935. Before the end of the year they learnt that he was not the sole inventor, but pressed ahead with the purchase and helped him secure a patent, while they bought up the patents to similar games – including The Landlord’s Game – to ensure that they had definitive ownership of the idea.
