The Whopper was created in 1957 by Burger King co-founder James McLamore and originally sold for 37¢ (US$3.26 adjusted for inflation). McLamore created the burger after he noticed that a rival restaurant in Gainesville, Florida was succeeding by selling a larger burger. 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"". 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.
