The soft-serve formula was first developed in 1938 by Douds, Iowa-born John Fremont "J.F." "Grandpa" McCullough (1871‒1963)^[10] and his son Alex. They convinced friend and loyal customer Sherb Noble to offer the product in his ice cream store in Kankakee, Illinois.^[11] On the first day of sales, Noble dished out more than 1,600 servings of the new dessert within two hours.^[12] Noble and the McCulloughs went on to open the first Dairy Queen store in 1940 in Joliet, Illinois.
While this Dairy Queen has not been in operation since the 1950s, the
building still stands at 501 N Chicago St. as a city-designated
landmark.^[13] Since 1940, the chain has used a franchise
system to expand its operations globally. The state with the most Dairy
Queen restaurants is Texas. The Texas Dairy Queen Operators' Council
facilitates marketing and the food system in Texas. Dairy Queen
International is the parent company of Dairy Queen. In the United
States, it operates under American Dairy Queen.^[14][15] IDQ is a wholly owned subsidiary of Berkshire Hathaway.
At the end of its fiscal year 2014, Dairy Queen reported over 6,400
