Bar Codes & Mad Magazine

Jason English

If you've done any Googling this morning, you probably know today is the 57th anniversary of the first bar code patent.

From The Christian Science Monitor:

On October 7, 1952, inventors Norman Woodland and Bernard Silver were granted the first patent for their invention. 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.

As long as we're on the subject, let's take a look back at a couple Mad Magazine issues that drew attention to the UPC symbol they were forced to stick on the cover, starting in 1978:

The Japanese firm D-Barcode has been adding a little life to the plain old UPC symbols. For lots more examples, check out this cool round-up of bar codes Dark Roasted Blend put together last year.
