Step 1 : Introduction to the question "Which burger chain trademarked the name “slyders”?"
Sliders are one of the hallmarks of American cuisine and it was originally used to describe the onion-steamed small burgers at White Castle restaurants. White Castle is widely credited as the country's first fast-food chain. Often referred to as "sliders", the burgers were initially priced at five cents. White Castle was granted a U.S. trademark on the spelling variant "slyder" which derived from the way the burgers slide out of their cardboard boxes. On January 14, 2014, Time labeled the White Castle slider the most influential burger of all time.
