The Big Mac became McDonald’s first global signature sandwich. Created by franchisee Jim Delligatti, it was introduced in 1967 in the Pittsburgh area and rolled out nationally in the United States in 1968.
Its three-part bun, two beef patties, special sauce, lettuce, cheese, pickles, and onions gave McDonald’s a distinctive flagship product. The sandwich became an important branding asset because customers could recognize and request it across markets.
The Big Mac is sometimes confused with the Quarter Pounder, which has a different construction and a separate product history. The Filet-O-Fish also predates the Big Mac, but it was developed as a fish sandwich rather than as McDonald’s signature global burger.
The sandwich’s name and standardized presentation helped turn a menu item into a major part of McDonald’s corporate identity.
