The Big Mac was introduced nationally by McDonald’s in 1968 and became one of its best-known branded menu names.
The hamburger was created by Jim Delligatti, a McDonald’s franchisee in the Pittsburgh area. It used two beef patties, a middle bun section, lettuce, cheese, pickles, onions, and a special sauce. The layered construction made the product visually distinctive and gave McDonald’s a major signature item.
The Big Mac name is part of the product’s branding history, not simply a description of its size. McDonald’s used the name in menus, packaging, advertising, and later international marketing. The sandwich became closely associated with the company’s identity alongside the Golden Arches and its advertising characters.
The Big Mac is sometimes confused with the Quarter Pounder because both are major McDonald’s hamburger brands. The Quarter Pounder is defined by the weight of its beef patty before cooking, while the Big Mac is defined by its two-patty layered format and distinctive sauce.
