Happy Birthday, Bar Codes [Video]

Someone bought a pack of chewing gum at a Marsh Supermarket in Troy, Ohio, this very day. It was the first purchase of an item to be scanned into a cash register using the Universal Product Code.
The Census Bureau shared that tidbit, and I thought that's something I wouldn't even think about. No way I thought that was that old.
