The Big Mac was the McDonald’s sandwich branded with the famous “Two all-beef patties” jingle.
The jingle described the Big Mac’s signature construction: two beef patties, special sauce, lettuce, cheese, pickles, and onions on a sesame-seed bun. Its compact list made the product’s ingredients memorable and became one of the best-known examples of fast-food advertising.
Jim Delligatti, a McDonald’s franchisee, created the sandwich in 1967. McDonald’s introduced it nationally in the United States in 1968, turning the product into one of the company’s most enduring menu brands.
The jingle is sometimes remembered as a general McDonald’s slogan, but it specifically promoted the Big Mac. It also described the sandwich’s ingredients rather than the company’s broader corporate identity.
