On June 26, 1974, the first UPC bar code was scanned on a package of Wrigley's chewing gum at a Marsh supermarket in Ohio. Its price was automatically registered by an electronic scanner, and the era of the bar code began. Time magazine praised the UPC code as the "miracle-chip brain of the check-out computer" by electronically keeping track of inventory. What happened to that first pack of Wrigley's gum that passed under the rays of a bar code scanner? Forbes reported in 2002 that it rests safely on display at the Smithsonian's National Museum of American History. Some trivia: the earliest bar codes were used on the sides of railroad cars in the mid-1960s. When the package of Wrigley's officially beeped through a bar code scanner in 1974, it was the first commercial use of a bar code on a consumer product, and the realization of a dream hatched in 1948 by Bernard Silver, a graduate student at Drexel. In the early 1970s, supermarkets saw the need for bar codes. "After weighing proposals, the committee chose the universal product code, or UPC, an IBM design......". Once codes and scanning machines began popping up across the U.S., the number and variety of products in grocery stores expanded rapidly. The new technology also allowed retailers to adjust the prices of their products based on inflation. Further explanation/details in the vid.
