The Big Mac introduced the “Big Mac” name to McDonald’s brand in 1968.
McDonald’s introduced the hamburger in 1968 as a larger, two-patty sandwich with a middle bun layer. It was created by franchisee Jim Delligatti, who operated restaurants in the Pittsburgh area. The product gave McDonald’s a distinctive premium-style menu item that could be advertised separately from its standard hamburger.
The name became a major branding asset because it was short, memorable, and strongly associated with McDonald’s. The sandwich’s special sauce, layered construction, and sesame-seed bun also helped distinguish it from ordinary hamburgers.
The Big Mac should not be confused with the Quarter Pounder, which is identified by patty weight, or the later McRib. The Big Mac’s 1968 introduction is the relevant milestone for the product name and its place in McDonald’s branding history.
