The Origin of the American Supermarket: Before 1916, Touching The Merchandise Was Not Allowed

This video explains the origin of the American supermarket — who invented self-service grocery retail, how the concept was patented, and why the store layout Clarence Saunders designed in Memphis in 1916 is the spatial logic governing every supermarket, big box store, airport terminal, IKEA, and Amazon fulfillment center operating today. On September 6, 1916, a Memphis Tennessee grocery operator named Clarence Saunders opened a store at 79 Jefferson Avenue in which customers were, for the first time in American commercial history, permitted to select their own merchandise from open shelves, place it in a wire basket, and carry it to a dedicated checkout station at the exit. Saunders called the store Piggly Wiggly and patented the design as US Patent 1,242,872 in 1917, describing a self-serving store in which the customer follows a controlled path through merchandise to a checkout at the exit. This video traces how that single store layout became the operating architecture of modern retail, how Saunders made and lost a ten-million-dollar fortune in a Wall Street short-selling battle in 1923, how his 1937 automated grocery concept called the Keedoozle anticipated Amazon Go by 81 years, and how the behavioral economics principle he built into the 1916 patent won a Nobel Prize in Economics in 2017 under the name choice architecture. What's covered in this video: The American clerk-service grocery model that preceded Piggly Wiggly required customers to state their order to a clerk across a counter barrier, with no direct access to merchandise, a system unchanged since the colonial general store era. Clarence Saunders, born in Amherst County Virginia in 1881, worked as a grocery clerk from age fourteen and later as a Memphis wholesale grocer before identifying the labor cost inefficiency of the clerk-service transaction model. Piggly Wiggly Number One opened September 6, 1916, on Jefferson Avenue in Memphis Tennessee, featuring an entrance turnstile, open shelving with forward-facing labeled products, a serpentine maze of aisles, and a dedicated checkout station at the exit. US Patent 1,242,872, filed October 21, 1916 and granted October 9, 1917, describes the self-serving store design and encodes the spatial principle that the customer must pass all merchandise before reaching the checkout. By 1922, Saunders had franchised the Piggly Wiggly concept to 1,200 stores across 29 states, applying franchise standardization logic 38 years before Ray Kroc applied the same model to McDonald's. In 1922 and 1923, Saunders attempted to corner the Piggly Wiggly stock market position against Wall Street short-sellers, the New York Stock Exchange granted the short-sellers a position extension, and Saunders went bankrupt in spring 1923, losing both the Piggly Wiggly company and his unfinished Pink Palace mansion in Memphis. Saunders launched a second grocery chain called Clarence Saunders Sole Owner of My Name Stores in 1925, reached approximately 200 locations by 1927, and lost this business in the Great Depression by 1929. In 1937, Saunders opened the Keedoozle in Memphis, a fully mechanized grocery store in which products were displayed behind glass panels and released to a conveyor belt by an electric key, anticipating the cashierless retail concept Amazon deployed as Amazon Go in Seattle in January 2018. The Piggly Wiggly maze design is the direct architectural ancestor of IKEA's single-path serpentine showroom layout, airport duty-free concourse design, Disney's Main Street USA retail entry corridor, and Amazon fulfillment center picker-path algorithms. Between 40 and 60 percent of all supermarket purchases are unplanned at store entry, an economic engine made possible by the direct product exposure the self-service layout creates. Richard Thaler and Cass Sunstein published Nudge in 2008, describing choice architecture as the influence of environment design on decisions; Thaler received the Nobel Prize in Economics in 2017, citing this work, for a principle Saunders encoded in a patent application in 1916. Saunders died October 14, 1953, with blueprints for his final automated grocery concept, the Foodelectric, unfinished on his desk; the Pink Palace, purchased by the city of Memphis, is now the Memphis Pink Palace Museum and contains a full-scale replica of the original Piggly Wiggly store.
