c) Piggly Wiggly

Piggly Wiggly, founded in 1916 in Memphis, Tennessee, by Clarence Saunders, was the first true self-service grocery store and is considered the first supermarket chain in the U.S. Saunders’ innovation transformed the grocery shopping experience, introducing features like shopping baskets, open shelves, and no clerks to fetch goods. Piggly Wiggly’s model set a new standard for grocery retail, leading to greater efficiency and lower costs, and revolutionized the way people shopped for food, influencing the development of the modern supermarket industry.
