The Bar code was invented on Oct 7 1952 in The United States, but the technology took off 20 years after when Laser Sensors were invented. Today on Google's website you can see they replaced the Google logo to a Bar Code that reads Google.
The first product that used a Bar Code was Wrigley's Gum. Now there is a Bar Code for every product available in the market. Those little stripes contain information about the product, price, manufacturer information. etc.
