At the height of America's Great Depression, Monopoly was the best selling game in the country. Since then, Monopoly has appeared in 40 countries and 25 foreign languages. Parker Brother based its initial deluxe version on Charles Darrow's own deluxe version, packed in the famous "white box." By 1961 only the white box version was available, and it still bore a strong resemblance to Parker's and Darrow's earlier editions.
