The candy business underwent a drastic change in the 1830s when technological advances and the availability of sugar opened up the market. The new market was not only for the enjoyment of the rich but also for the pleasure of the working class. There was also an increasing market for children. While some fine confectioners remained, the candy store became a staple of the child of the American working class. Penny candies epitomized this transformation of candy. Penny candy became the first material good that children spent their own money on. For this reason, candy store-owners relied almost entirely on the business of children to keep them running. Even penny candies were directly descended from medicated lozenges that held bitter medicine in a hard sugar coating.
