Internetnews announced some of the additional features Google has added, including USPS codes, UPC codes, Flight codes, and zip codes. Thats a whole lot of codes!

In addition the article briefly talks about how Google can make additional revenue off of the Flight numbers and UPC codes.

"When you type in the UPC code, it comes out with a link to Upcdatabase.com but some other information as well," Li said. "It's mining the information that Google has in its example but also information about the product as well. If I'm either the product manufacturer or a competitor, I could go to Google and buy my UPC number."
