As 7-Eleven became more successful, it sought to introduce more “original” products. In 1965, they began a licensing deal with The ICEE Company under two conditions: 7-Eleven must use a different name for their product, and they were only allowed to sell it at 7-Eleven locations.
Inspired by the drink’s ability to induce an oral symphony, Bob Stanford, 7-Eleven’s agency director at the time, re-named it the “Slurpee.”
