On this episode of Our American Stories, you may see them everywhere today, but the UPC barcode didn’t become commonplace until well into the 1970s. What had started as a simple idea to speed up checkout lines took decades to develop, requiring advances in computing, scanning tech, and cooperation across different industries.

When the first barcode was scanned in 1974, it marked the beginning of a silent revolution. Retailers could track inventory more accurately, businesses could move products more efficiently, and everyday shopping was transformed in ways most people never noticed.

Our regular contributor, The History Guy, shares the story of the barcode, how it came to be, why it took so long to catch on, and how it changed the way the world buys and sells goods forever.
