The surprising history of the barcode
  + stars: | 2024-01-18 | by ( Jordan Frith | Clemson University | ) edition.cnn.com   time to read: +7 min
The bull’s-eye barcode introduced in Woodland and Silver’s 1949 patent. Despite being the first barcode to be officially adopted by an industry, the multicolored design of the Kartrak symbol is now just a footnote in history. The seven barcode symbol finalists displayed in the official internal reports of the symbol selection committee. The bull’s-eye barcode, after all, was the original barcode symbol, and RCA was a powerful company that had invested significant resources in developing the technology. RCA’s main competitor was a latecomer to the battle for barcode dominance: the IBM symbol invented in the early 1970s by George Laurier.

The barcode, that rectangle of thick and thin parallel lines seen on seemingly every grocery product, package, prescription bottle and piece of luggage is turning 50 years old. There’s hardly any products now that don’t use a barcode for identification.”Who got there first? A replica of a package of Wrigley's Juicy Fruit Chewing Gum used in a Smithsonian museum exhibition. The Wall Street Journal, in a 2022 obituary of Collins, gives the nod of inventing the barcode to him. Years later, the Smithsonian had a replica of that Wrigley’s gum installed in a museum exhibition on the history of the barcode.
