May is National Hamburger Month, and White Castle has a lot to celebrate. Besides being the first fast-food hamburger chain in the U.S. and the pioneer of the smaller-sized burger that ultimately became known as The Original Slider, the 101-year-old family-owned business has recently reached a significant milestone: all-time sales of its burgers—The Original Slider and Cheese Slider—have surpassed 28 billion. That includes 22 billion sliders sold in restaurants and another 6 billion sold through the company's retail division.
"This is a memorable moment for White Castle, and what better time to celebrate than National Hamburger Month," said Jamie Richardson, vice president at White Castle. "We played an essential part in the introduction of the hamburger over 100 years ago. It's rewarding to see our numbers climb, reinforcing our role in the enduring popularity of the hamburger."
