The Big Mac inspired the McDonald's advertising jingle that spells out its ingredients.
The sandwich was created by franchisee Jim Delligatti and introduced in 1967. Its distinctive construction includes two beef patties, special sauce, lettuce, cheese, pickles, onions, and a sesame-seed bun. That unusual combination made it especially suitable for a short, repeatable musical description.
The phrase commonly known as the Big Mac jingle lists the sandwich's components in a fixed sequence. It became one of McDonald's most memorable examples of product branding because customers could recall both the name and the ingredient order.
The Big Mac jingle is sometimes mistaken for a general McDonald's slogan. It was specifically tied to the Big Mac, unlike broad campaigns such as You Deserve a Break Today. The sandwich's three-part bun and special sauce also distinguish it from the Quarter Pounder, which has a different patty size and construction.
