<Tr> <Th> Parent </Th> <Td> Hasbro </Td> </Tr> <P> Parker Brothers was an American toy and game manufacturer which later became a brand of Hasbro . More than 1,800 games were published under the Parker Brothers name since 1883 . Among its products were Monopoly, Cluedo (licensed from the British publisher and known as Clue in North America), Sorry!, Risk, Trivial Pursuit, Ouija, Aggravation, Bop It and Probe . 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> <P> Parker founded his game company, initially called the George S. Parker Company, in his hometown of Salem, Massachusetts in 1883 . When George's brother Charles joined the business in 1888, the company's name was changed to its more familiar form . In 1898 a third brother, Edward H. Parker, joined the company . For many years, George designed most of the games himself, and wrote all the rules . Many games were based on important events of the day: Klondike was based on the Alaskan gold rush, and War in Cuba was based on the impending Spanish--American War . </P>
