The Barcode


Today is the 57th anniversary of the first patent on the bar code. Inventors Norman Woodland and Bernard Silver filed the patent in October 1949, and it was granted, No. 2,612,994, on October 7, 1952. The original patent was for a system that would encode data in circles (a bulls eye pattern), so that it could be scanned in any direction. To celebrate the fact, Google have replaced their distinct logo with a barcode. Not to be outdone by the search engine giants, so have the Frog Blog!
