Dairy Queen (DQ) is an American fast food chain of soft serve ice cream and fast food restaurants owned and operated by International Dairy Queen, Inc. (a subsidiary of Berkshire Hathaway since 1998), which also owns Orange Julius, and formerly owned Karmelkorn and Golden Skillet Fried Chicken. It serves a variety of its own original frozen products that vary from location to location.
The Dairy Queen story begins in 1938, two years before the restaurant opened, with the dawn of soft-serve ice cream. The inventors, J.F. McCullough and his son Alex convinced ice cream man Sherb Noble to sell it at his shop in Kankakee, Illinois. It was an immediate hit. They served 1,600 customers in two hours at an all-you-can-eat ice cream sale.
Noble and the McCulloughs opened the first Dairy Queen store (pictured above) on June 22, 1940, along historic Route 66 in Joliet, Illinois. Though no longer serving customers, the site still stands as a local landmark.
Dairy Queen’s first menu items included soft-serve cones, sundaes and ice cream by the pint and quart. A cone cost a nickel, and a sundae cost 8 cents.
