The Big Mac was the McDonald’s product promoted by the jingle describing “two all-beef patties” and the sandwich’s other ingredients.
The advertisement listed the Big Mac’s components in a memorable sequence: two beef patties, special sauce, lettuce, cheese, pickles, onions, and a sesame-seed bun. The musical wording helped customers remember both the product name and its distinctive construction.
The jingle became an important example of product-centered McDonald’s branding. Rather than relying only on a broad corporate slogan, it gave a specific menu item its own verbal identity. The campaign is generally associated with 1974 advertising.
The phrase is sometimes incorrectly attributed to the Quarter Pounder because both products are signature hamburgers. The ingredient list, especially the two patties and special sauce, identifies the Big Mac.
