Google Bar Code

Today's Google logo is a bar code, that says "Google" in Code 128 which is a standard way of encoding strings of ASCII characters in a barcode. Today marks the 57th anniversary of the first patent on the bar code.

Inventors Norman Woodland and Bernard Silver filed a patent in October 1949, and was granted, No. 2612994. The original patent was for a system that encodes data in circles, basically a pattern of a bulls eye, so that could be scanned in any direction. You may have seen them on some older products.

It is very hard not to find a product without a bar code these days in a store. Amazing how big a role bar codes play in our marketplace and digital economy. I can't imagine a world without them.
