Pi in the sky…
As we watch sheep chase ice cream cones across the summer sky, we might recall that on this date in 1974, at 8:01 a.m., a “10-Pak” of Juicy Fruit chewing gum with a bar code printed on it was passed over a scanner at the Marsh Supermarket in Troy, Ohio– and became the first product ever logged under the new Universal Product Code (UPC) computerized recognition system.
Sharon Buchanan (pictured above 30 yrs later) performed the first ever bar code scan when she rang up this 10-pack of Wrigley’s Juicy Fruit gum, which is now at the Smithsonian. (source)
