The Big Mac was first introduced by McDonald's in the metropolitan area of Pittsburgh in 1967 and nationwide in 1968. The Big Mac had two previous names, both of which failed in the marketplace: The Aristocrat, which consumers found difficult to pronounce and understand, and Blue Ribbon Burger. The third name, Big Mac, was created by Esther Glickstein Rose, a 21-year-old advertising secretary. The name was popularized by a 1974 advertising campaign featuring a list of the ingredients in a Big Mac: "Two all-beef patties, special sauce, lettuce, cheese, pickles, onions – on a sesame seed bun."
