Dairy Queen started making Blizzards in 1985, but they’ve had the trademark for “Blizzard” since the '50s
Back then, a Blizzard was just a really thick milkshake, without the distinctive extra pieces that have come to define the dessert. Since 1985, “Blizzard” has specifically referred to a dessert with blended fruit, candy, nuts, or cookies inside. Without the candy, a Blizzard used to be called “concrete” because of it’s thickness, but they have since dropped that name. There are more than 75 Blizzard flavors, and in China they even have a green tea Blizzard.
