Big Mac turns 40

The Big Mac was first introduced in 1967 by Jim Delligatti, a McDonald's franchise owner in Uniontown, Pennsylvania. A year later, it became a staple of McDonald's menus across the country.
To celebrate the burger's anniversary, Delligatti, 89, and his family opened a Big Mac Museum Restaurant this week in North Huntingdon, Pennsylvania, full of memorabilia, celebratory exhibits and the world's largest Big Mac statue.
