Whatchamacallit is the name of a candy bar made by The Hershey Company. This candy bar was first introduced in 1978. Since then, Whatchamacallit has included peanut-flavored crisp with a layer of caramel and a layer of milk chocolate coating.
In the late 80s, a commercial was created in a New Wave style referring to the bar in various ways to say "whatchamacallit", including names that had been made-up, such as "wowzamadoo". In Canada, an identical chocolate bar is marketed by Hershey's as "Special Crisp", but is found much less frequently on candy racks in Canada than "Whatchamacallit" is in the United States. 1978 WHATCHAMACALLIT candy bar is introduced.1987 WHATCHAMACALLIT candy bar was reformulated and caramel was added.2002 King Size introduced.2002 New brand graphics.
