The product is first served at an All You Can Eat sale in Kankakee, Illinois. Dairy Queen started off by selling cold and frozen treats that attracted many customers. A popular Dairy Queen item is the Blizzard, which is soft-serve mechanically blended with mix-in ingredients such as sundae toppings and/or pieces of cookies, brownies, or candy. It has been a staple on the menu since its introduction in 1985, a year in which Dairy Queen sold more than 100 million Blizzards. The Oreo Blizzard is one of the most popular flavors of Blizzard due to its delicious combination of vanilla soft serve and Oreo cookie pieces.
The very first Dairy Queen was created in 1940 in Joliet, Illinois. The founder was John Fremont McCullough. They convinced friend and loyal customer Sherb Noble to offer the product in his ice cream store in Kankakee, Illinois. On the first day of sales, Noble sold more than 1,600 servings of the new dessert within two hours. Noble and the McCulloughs went on to open the first Dairy Queen store in 1940 in Joliet, Illinois.
