The trade name is now defunct; former products are marketed under the "Hasbro Gaming" label . </P> <P> Parker Brothers was founded by George S. Parker . Parker's philosophy deviated from the prevalent theme of board game design; he believed that games should be played for enjoyment and did not need to emphasize morals and values . He created his first game, called Banking, in 1883 when he was 16 . Banking is a game in which players borrowed money from the bank and tried to generate wealth by guessing how well they could do . The game included 160 cards which foretold their failures or successes . The game was so popular among family and friends that his brother, Charles Parker, urged him to publish it . George approached two Boston publishers with the idea, but was unsuccessful . Not discouraged, he spent $40 to publish 500 sets of Banking . He eventually sold all but twelve copies, making a profit of $100 . </P>
