A gumball machine is a type of bulk vending machine that dispenses individual gumballs in exchange for money. They were developed around the early twentieth century. History. Although vending machines for stick or block-shaped gum were seen as early as 1888, the first machines to carry actual gumballs were not seen until 1907 (probably released first by the Thomas Adams Gum Co. in the United States). Patented in 1923, the Norris Manufacturing Company produced their "Master" line of chrome gumball machines during the 1930s. These machines could accept either pennies or nickels.
