[2][3] The ice cream was packed in metal-lined wooden containers that the Hershey brothers designed and built.

Salesmen traveled daily routes to deliver product to customers in the county and in surrounding areas.

Marrow had a large facility in Lancaster at 425-429 East Orange Street, and was making up to 450 gallons of ice cream per day.

[2][3] During the Great Depression, the company became the first ice cream maker to offer its products in pre-packaged pints.

[4][5] Following World War II, the company continued to answer the call for greater convenience in consumer foods and expanded its offerings to include single-serve, easy to eat items such as ice pops and ice cream sandwiches.

While local orders continued to be delivered in small Hershey's Ice Cream refrigerated trucks, the company shifted to transporting most of its ice cream to refrigerated tractor trailer trucks, enabling it to stretch its market beyond the state of Pennsylvania.

[4][6] In 1998, operations were modernized and automated when the company purchased 105 acres (0.42 km2) in nearby Middletown where it constructed a modern 1.3 million cubic foot warehouse, enabling it to boost its efficiency, reducing the need to increase its summer workforce, and reducing the frequent product loss caused by hand orders and inefficient packing systems.

The modernization of its warehouse also improved inventory management, order accuracy, and has helped the company continue its growth.

Milton S. Hershey learned of the candies in 1919, and assigned Charles Ziegler to "find instances of confusion and infringement and of unfair competition".

[8] After cease and desist letters failed to resolve the problem, Milton Hershey filed suit in 1921 in U.S. District Court for trademark infringement.

After three years in court, the two companies again settled, with Hershey Creamery agreeing to put a disclaimer on all of its products, corporate website, and in promotional materials and press releases.

The charges were brought by the Environmental Protection Agency (EPA), which stated that the company failed to develop the required plans with regard to its storage and use of anhydrous ammonia, which is a regulated substance.

Hershey Creamery complied and in April 2007 submitted the appropriate RMPs, which were confirmed to be in-place through subsequent inspection.

The case was heard at the Federal Middle District court of Pennsylvania, with Hershey Creamery pleading guilty to the charges; it was subsequently fined $100,000 and given a year probation.

[11] Hershey Creamery is a family operated business, with each new generation raised to assume roles within the company hierarchy upon graduation of high school.

It opened a distribution center there in 1998, and plans to shift its headquarters and production facilities there over the next five to ten years.

[9] Sales are primarily derived from branded ice cream parlors, quick-serve restaurants, and the distribution of its pre-packaged items to convenience stores, food service operators such as schools, hospitals, prisons, military installations, sports stadiums, amusement parks, and assisted living centers.

[20] As of 2009[update], Hershey Creamery Company offered 108 flavors of regular, hand-dipped premium ice cream, with 31 of those varieties marked as super premium gold rim products and 4 available in no sugar added (NSA) varieties that use the alternate sweetening product Splenda.
