Dunkin'[n 1] is an American multinational coffee/donut company and quick service restaurant. It was founded by William Rosenberg in Quincy, Massachusetts in 1950. The chain was acquired by Baskin-Robbins' holding company Allied Domecq in 1990; its acquisition of the Mister Donut chain and the conversion of that chain to Dunkin' Donuts facilitated the brand's growth in North America that year. Dunkin' Donuts and Baskin-Robbins have been subsidiaries of Dunkin' Brands, headquartered in Canton, Massachusetts, since 2004. The chain began rebranding as a "beverage-led company", and was renamed Dunkin', in January 2019.
