Google doodle celebrates invention of Bar Code
The barcode that Google has placed on its homepage describes it in Code 18, a standard used to convert ASCII characters into a bar code. Google has been regularly changing its logo on festivals, landmark events and special occasions.
A LARGE number of people were surprised, when they did not find the popular Google doodle on the search engine's home page on Wednesday (October 7) . Instead, Google has put a bar code on its home page to mark the 57th anniversary of the first Bar Code patent granted on October 7, 1952.
The patent was granted to Norman Woodland and Bernard Silver, who had filed it three years earlier for a system that would encode data in circles, making it scan-able in any direction.

Although, the bar code patent was granted in 1952 but, the manner in which it is used now is largely due to the research by this year's Nobel Prize winners in Physics, George Smith, Charles Kao and Willard Boyle.
The research by the trio enabled the development of a technology for electronic reading of the bar code.
