A Slurpee is a frozen flavored drink sold by the 7-Eleven company. In 1967, 7-Eleven licensed the product from the ICEE Company, and began selling it as the Slurpee. Machines to make frozen beverages were invented by Omar Knedlik in the late 1950s. The idea for a slushed ice drink came when Knedlik's soda fountain broke down, forcing him to put his sodas in a freezer to stay cool, which caused them to become slushy. Many people loved them, which gave him the idea to make a machine to help make a 'slushy'. When it became popular, Knedlik hired artist Ruth E. Taylor to create a name and logo for his invention. She created the ICEE name and designed the original logo, which is used today. Early prototypes for the machine made use of an automobile air conditioning unit.
