Happy Birthday Big Mac! Signature McDonald's Burger Turns 50

More than a billion Big Macs are consumed around the world each year.

One of the world’s most popular sandwiches is turning 50 this week. 

The McDonald’s Big Mac was created in 1968 by Jim Delligatti, who wanted "double of everything." 

Today, more than a billion Big Macs are consumed around the world each year.

“When my great-grandfather Jim Delligatti, invented the Big Mac at his grill in Uniontown, Pennsylvania, he just wanted to make his local customers happy,” Nick Delligatti, a fourth-generation McDonald’s owner-operator, said in a statement.

To celebrate the milestone, McDonald's customers can receive a MacCoin with the purchase of a Big Mac across the U.S. beginning at lunch time on Aug. 2 while supplies last. Then, on Aug. 3 through the rest of the year, customers can redeem their MacCoin for a free Big Mac at participating McDonald’s restaurants in the U.S. and in more than 50 participating countries.

And no one is probably more excited than Don Gorske, a man who has eaten more than 30,000 Big Macs in his lifetime. He even buys them in bulk.

Gorske is the recipient of a Guinness World record for his major feat.

McDonald’s revealed the ingredients for the special Big Mac Sauce in 2012: mayo, sweet pickle relish, yellow mustard, vinegar, garlic powder, onion powder and paprika.

They also previously revealed the sandwich was originally going to be called “The Aristocrat” but was renamed Big Mac by a young secretary working for the company at the time.
