Few products in the history of product and packaging design can boast the success and longevity of Hershey's Kisses. Distinctive. Convenient. Readily recognized by consumers, young and old. Love for this bite–size milk chocolate treat has led to the sale of more than 12 billion Hershey's Kisses annually.

What's more, the familiar shape, size and silver foil packaging of Hershey's Kisses have remained virtually unchanged since first introduced in 1907. Initially, the candy was wrapped in silver foil by hand, but in 1921, automated wrapping machines took over the task and the trademark "plume" was added.

For nearly 90 years, Hershey has steadily supplied the world with Kisses—except during World War II when silver foil rationing interrupted production.

While it's not known exactly how Hershey's Kisses got its name, popular theory says the candy was named for the sound or motion of the chocolate being extruded during the manufacturing process. Customers prefer to think of the name more romantically, and Hershey's has complied with red and silver foil Kisses for Valentine's Day (as well as appropriately colored foils for seasonal holidays), and Hershey's Hugs, mini–Kisses hugged by white chocolate.
