 Several people, mostly in the midwestern United States and near the East Coast of the United States, contributed to the game's design and evolution.By the 1970s, the idea that the game had been created solely by Charles Darrow had become popular folklore; it was printed in the game's instructions for many years, in a 1974 book devoted to "Monopoly", and was cited in a general book about toys even as recently as 2007.Even a guide to family games published for "Reader's Digest" in 2003 only gave credit to Darrow and none to Elizabeth Magie, 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.
