In the 1990s, investors bought Dairy Queen stores that were individually owned, intending to increase profitability through economies of scale. Using the 2010 census, the state with the most Dairy Queen restaurants per person is Minnesota. In the US, the state with the most Dairy Queen restaurants is Texas. The first store in Canada opened in Melville, Saskatchewan, in 1953.

Since 1940, the chain has used a franchise system to expand its operations globally. It closed in the 1950s, but the building at 501 N Chicago Street is a city-designated landmark. Noble and the McCulloughs went on to open the first Dairy Queen store in 1940 in Joliet, Illinois. On the first day of sales, Noble sold more than 1,600 servings of the new dessert within two hours. They convinced friend and loyal customer Sherb Noble to offer the product in his ice cream store in Kankakee, Illinois.

The soft-serve formula was first developed in 1938 by John Fremont 'J.F.' McCullough and his son Alex. It serves a variety of its own original frozen products that vary from location to location. It was owned and operated by Sherb Noble and opened on June 22, 1940.
