On June 26, 1974, at a Marsh supermarket in Troy, Ohio, a 10-pack of Wrigley's Juicy Fruit gum became the first retail item scanned using a Universal Product Code, ringing up for 67 cents. The pack was chosen partly by chance, and it is now held in the Smithsonian, marking the barcode's transition from industry proposal to live commercial infrastructure.
The barcode became culturally invisible precisely because it worked so consistently that people stopped noticing it, a fate the book treats as the hallmark of successful infrastructure rather than failure. Technologies that recede from attention are often the ones exerting the most pervasive influence on daily life.
The barcode's power came not from the symbol itself but from the industry-wide agreement to a single shared standard (the UPC), which required competing retailers and manufacturers to cooperate before any individual benefit existed. Without this coordinated standardization, the scanning technology would have fragmented into incompatible systems and failed to spread.
Viewing everyday products as nodes in an information system reveals that the barcode transformed physical goods into machine-readable data, enabling inventory tracking, pricing automation, and supply-chain logistics far beyond the checkout line. Seen this way, a can of soup is less an object than an entry in a vast relational database made legible to machines.
