Now, more than 10 billion bar codes are scanned in 25 industries and in places including airports, hospitals, and shipping centers, according to Motorola. In 1974, a scanner in a Marsh supermarket in Troy, Ohio, met the simple black-and-white striped bar code design tacked onto a 10-piece pack of Juicy fruit gum. The only difference between the bar code we know today and the one Woodland and Silver invented was that it was comprised of a series of concentric circles, not the 59 black-and-white vertical lines synonymous with the current design.Įarlier this year, on June 26, the bar code celebrated its 35th birthday. On October 7, 1952, inventors Norman Woodland and Bernard Silver were granted the first patent for their invention. Today, the usual Google logo has been replaced by the ubiquitous black-and-white bar code design to celebrate the 57th anniversary of the first bar code patent.
