The Chunky candy bar was introduced in the late 1930s by New York City candy maker, Philip Silvershein. Looking for a name for his candy bar, then made with cashews, chocolate, raisins and Brazilian nuts, he decided on Chunky, the nickname of his "chunky" granddaughter.
Supposedly, the original shape of the candy was a pyramid, but after packaging difficulties developed, the top was cut off, creating the candy's distinctive shape that remains to this day.
An early 1970s TV commercial for Chunky showed a young boy watching TV with his father. The boy amused viewers by claiming that Chunky was "THICKER-ER."
Other Chunky advertising slogans included "Chunky, What a Chunk of Chocolate" and "Open Wide for Chunky".
