Dunkin'

William Rosenberg opened the first location in Quincy, Massachusetts, back in 1950, serving fresh coffee and glazed rings to hungry locals. The brand grew steadily until Allied Lyons bought it in 1990 alongside Baskin-Robbins. That same year, the company swallowed up Mister Donut, converting those locations to the Dunkin' name and fueling rapid expansion across North America.

In January 2019, the company dropped 'Donuts' from its name to highlight its identity as a drink-focused business. Late that decade, Inspire Brands purchased the entire group for approximately $3.8 billion, bringing Dunkin' under the same corporate umbrella as Arby's and Baskin-Robbins.

The chain continues aggressive growth with new locations scheduled for markets like Muskegon, Michigan, set to open by the end of 2026. Recent partnerships include a collaboration with pretzel brand Flipz for a sweet and salty pumpkin spice offering in the fall of 2026. [edit]
