Which commercial product was the first to have a UPC bar code?

TabbyTom

The first bar codes were introduced at the Marsh Supermarket in Troy, Ohio, where the first bar-coded product to be scanned passed through the checkout at 8:01 a.m. on 26 June 1974. The historic item was Wrigley’s chewing gum, but historians are still arguing about whether it was a 10-pack or a single packet. (Copied from the New Shell Book of Firsts). Feb 21 06, 1:27 PM
