 The official Parker Brothers rules and board remained largely unchanged from 1936 to 2008.Ralph Anspach argued against this during an on-air conversation with "The Monopoly Book" author Maxine Brady in 1975, calling it an end to "steady progress" and an impediment to progress.Several authors who have written about the board game have noted many of the "house rules" that have become common among players, although they do not appear in Parker Brothers' rules sheets.
