At a Marsh Supermarket in Troy, Ohio, cashier Sharon Buchanan scanned a 10-pack of Wrigley's Juicy Fruit gum, the first retail transaction to use the newly standardized Universal Product Code. The barcode system, developed by IBM engineer George Laurer, went on to transform global retail, inventory management, and eventually logistics industries far beyond grocery stores.
The pack of Wrigley's Juicy Fruit gum scanned that morning in Troy, Ohio wasn't chosen by accident. Grocery industry engineers deliberately picked something small, because if the emerging barcode technology could be printed clearly enough to scan on a tiny gum wrapper, it could work on anything.
The Universal Product Code itself had been developed by IBM engineer George Laurer, who built on earlier barcode concepts to create the now-familiar pattern of black bars and white spaces encoding a 12-digit number. Laurer's design beat out a circular 'bullseye' barcode design partly because it printed more reliably on high-speed presses and smudged less.
Adoption was slow initially. Many retailers resisted the cost of new scanning equipment, and shoppers grumbled when stores stopped stamping prices on individual items, worried they were being deceived. But the efficiency gains proved undeniable: faster checkout lines, real-time inventory tracking, and eventually a foundation for entire industries of supply-chain logistics and even modern e-commerce fulfillment. That single scan of a gum pack in a small Ohio town is now recognized as one of computing's quietest, most consequential retail revolutions.
