The Whopper was created in 1957 by Burger King co-founder James McLamore and originally sold for 37¢ (US$3.26 adjusted for inflation).[1][2][3][4] McLamore created the burger after he noticed that a rival restaurant in Gainesville, Florida was succeeding by selling a larger burger.[5] Believing that the success of the rival product was its size, he devised the Whopper, naming it so because he thought it conveyed "imagery of something big".[6] Major fast food chains did not release a similar product, until the McDonald's Quarter Pounder and the Burger Chef Big Shef in the early 1970s.[6][7][8]
