 In four articles beginning October 9, two mention the "donut" spelling.Dunkin' Donuts, which was so-named in 1950, following its 1948 founding under the name Open Kettle (Quincy, Massachusetts), is the oldest surviving company to use the "donut" variation; other chains, such as the defunct Mayflower Doughnut Corporation (1931), did not use that spelling.According to the Oxford Dictionaries while "doughnut" is used internationally, the spelling "donut" is American.
