Hershey's Kisses were first introduced in 1907. The origin of the name is uncertain, but it may have had to do with the sound of chocolate being deposited during the manufacturing process. Kisses were wrapped by hand until a single-channel wrapper was introduced in 1921. Modern wrapping machines can wrap 1,300 Kisses per minute. The iconic plume sticking out of the wrapper bearing the name "Hershey" was introduced in 1924.
