Dunkin’ Donuts is an international doughnut and coffee retailer founded in 1950 by William Rosenberg in Quincy, Massachusetts; it is now headquartered in Canton. While the company originally focused on doughnuts and other baked goods, over half of its business today is in coffee sales, making it more of a competitor to Starbucks than to more traditional competitors such as Krispy Kreme and Tim Hortons.
