The Whopper is the signature hamburger brand of international fast food restaurant chain Burger King, its Australian franchise Hungry Jack's, and BK Whopper Bar kiosks. Introduced in 1957 in response to the large burger size of a local restaurant in Gainesville, Florida, it became central to Burger King's advertising, including the chain's tagline "the Home of the Whopper." Burger King's competitors began releasing similar products in the 1970s designed to compete against it.
