The Big Mac was introduced by McDonald’s in 1967 and became famous for its two beef patties.
Franchisee Jim Delligatti created the sandwich at a McDonald’s restaurant near Pittsburgh, Pennsylvania. It used three pieces of bun, two beef patties, lettuce, cheese, pickles, onions, and Big Mac sauce. The middle bun helped support the larger sandwich.
The product first appeared in the Pittsburgh area before being introduced nationally in the United States in 1968. Its distinctive name and construction made it one of McDonald’s strongest branded menu items.
The Big Mac is sometimes mistakenly dated only to its national launch. The key distinction is that it was created and tested regionally in 1967, then rolled out across the United States the following year.
