It also manufactures baked products, such as cookies, cakes, milk shakes, drinks and many more.Its headquarters are in Hershey, Pennsylvania, which is also home to Hersheypark and Hershey's Chocolate World. It was founded by Milton S. Hershey in 1894 as the Hershey Chocolate Company, a subsidiary of his Lancaster Caramel Company. The Hershey Trust Company owns a minority stake, but retains a majority of the voting power within the company.
Hershey's chocolate is available across the United States, and in over 60 countries worldwide. They have three mega distribution centers, with modern technology and labor management systems. In addition, Hershey is a member of the World Cocoa Foundation. It is also associated with the Hersheypark Stadium and the Giant Center.
After an apprenticeship to a confectioner in 1873, Milton S. Hershey founded a candy shop in Philadelphia. This candy shop was only open for six years, after which Hershey apprenticed with another confectioner in Denver, where he learned to make caramel. After another failed business attempt in New York, Hershey returned to Pennsylvania, where in 1886 he founded the Lancaster Caramel Company. The use of fresh milk in caramels proved successful, and in 1900, after seeing chocolate-making machines for the first time at the 1893 World's Columbian Exposition in Chicago, Hershey sold his caramel company for $1,000,000 (equal to $30,116,000 today), and began to concentrate on chocolate manufacturing, stating to people who questioned him, "Caramels are just a fad, but chocolate is a permanent thing."
In 1896, Milton built a milk-processing plant so he could create and refine a recipe for milk chocolate candies. In 1899, he developed the Hershey process, which is less sensitive to milk quality than traditional methods. In 1900, he began manufacturing Hershey's Milk Chocolate Bars, also called Hershey's Bars or Hershey Bars.
In 1903, Hershey began construction of a chocolate plant in his hometown of Derry Church, Pennsylvania, which later came to be known as Hershey, Pennsylvania. The town was an inexpensive place for the workers and their families to live; however the factory itself was built without windows so that employees would not be distracted. To increase employee morale, Milton provided leisure activities and created what would later become Hersheypark to make sure the citizens enjoyed themselves. The milk chocolate bars manufactured at this plant proved popular, and the company grew rapidly.
