According to the report, the town layout in 1914 had Hershey's enterprises occupying about 8,000 acres of Derry Township's nearly 17,500 acres of land. Today, even with the company's growth into a $6.6 billion franchise, Hershey's interests — The Hershey Co., the Milton Hershey School and Hersheypark — occupy about 11,000 acres in the township, Papson said.
