50 YEARS LATER | McDonald’s Big Mac has Pittsburgh roots

NEW YORK (AP) — McDonald’s is fighting to hold onto customers as the Big Mac turns 50, but it isn’t changing the makings of its most famous burger.

The company is celebrating the 1968 national launch of the double-decker sandwich whose ingredients of “two all-beef patties, special sauce, lettuce, cheese, pickles, onions and a sesame seed bun” were seared into American memories by a TV jingle. But the milestone comes as the company reduces its number of U.S. stores. McDonald’s said Thursday that customers are visiting less often. Other trendy burger options are reaching into the heartland.

The “Golden Arches” still have a massive global reach, and the McDonald’s brand of cheeseburgers, chicken nuggets and french fries remains recognizable around the world. But on its critical home turf, the company is toiling to stay relevant. Kale now appears in salads, fresh has replaced frozen beef patties in Quarter Pounders, and some stores now offer ordering kiosks, food delivery and barista-style cafes.

The milestone for the Big Mac shows how much McDonald’s and the rest of fast-food have evolved around it.

“Clearly, we’ve gotten a little more sophisticated in our menu development,” McDonald’s CEO Steve Easterbrook said in a phone interview.

As with many of its popular and long-lasting menu items, the idea for the Big Mac came from a franchisee.

In 1967, Michael James “Jim” Delligatti lobbied the company to let him test the burger at his Pittsburgh restaurants. Later, he acknowledged the Big Mac’s similarity to a popular sandwich sold by the Big Boy chain.

“This wasn’t like discovering the light bulb. The bulb was already there. All I did was screw it in the socket,” Delligatti said, according to “Behind the Arches.”

McDonald’s agreed to let Delligatti sell the sandwich at a single location, on the condition that he use the company’s standard bun. It didn’t work. Delligatti tried a bigger sesame seed bun, and the burger soon lifted sales by more than 12 percent.

After similar results at more stores, the Big Mac was added to the national menu in 1968. Other ideas from franchisees that hit the big time include the Filet-O-Fish, Egg McMuffin, Apple Pie (once deep-fried but now baked), and the Shamrock Shake.

“The company has benefited from the ingenuity of its small business men,” wrote Ray Kroc, who transformed the McDonald’s into a global franchise, in his book, “Grinding It Out.”
