Happy Birthday to Scanning

Again from Saveur, one of my favorite magazines, we learn that today is the anniversary of supermarket scanning. On June 26, 1974, at a Marsh's Supermarket in Troy, Ohio, "a ten-pack of Wrigley's Juicy Fruit gum became the first item to be scanned electronically at a checkout counter." Now there's a piece of food history trivia you can really use.
