As he worked long, hard days at a shipyard in Hingham, Massachusetts, during World War II, William Rosenberg was struck with an idea for a new kind of food service. As soon as the war ended, Rosenberg started Industrial Luncheon Services, a company that delivered fresh meals and snacks to factory workers. When Rosenberg realized that most of his business was in coffee and donuts, he quit offering his original service. He found an old awning store and converted it into a coffee-and-donut shop called The Open Kettle. This name was soon changed to the more familiar Dunkin' Donuts, and between 1950 and 1955 five more shops opened and thrived. The company later spread beyond the Boston area and has become the largest coffee-and-donut chain in the world.

Today, Dunkin' Donuts offers fifty-two varieties of donuts in each shop, but the most popular have always been the plain glazed and chocolate-glazed yeast donuts.
