When our parents, grandparents or great grandparents went grocery shopping, it sure looked different from today. Shops were smaller, the range of goods was limited and you couldn’t check what you needed for that special lasagna recipe on your smartphone in the middle of aisle 4!
But shopping also had a different sound back then. The monotone beeping at the check-out is something we are used to today. But it is the sound of one of the greatest supermarket innovations of the 20th century: I’m talking about the barcode-system. On 26 June 1974 the first product marked with a barcode was registered: It was a pack of “Juicy Fruit” gum in a supermarket in Ohio.
