Google: Organising the worlds knowledge

Internet is every where & Google is organizing the World's Knowledge.

Corporate Vision: "Google's mission is to organize the world’s information and make it universally accessible and useful."

Never before in history of humanity so much information was available at a finger tip. Year 2004 marked a revolution with the introduction of Google search Engine. Note the word "Universal”. Since from 2004, year the company went public, Google has been releasing a steady stream of innovative tools & services - some of them developed by Google's Engineers, many others brought in from acquiring start-ups: Google Search, Google Earth, Gmail, Orkut, Google Chrome, Google Docs & Spreadsheets, Blogger, Picasa, You Tube, Adsense, Adwords..... the list seemingly endless.

Initially it looked like random growth. But as the time passed, the above applications helped Google to gather more information and organize the pieces of knowledge. With the growing information at the Google Servers, the search results are helping people to find out the things they are looking for. With all this the Google, knows what the user needs the moment some one enters the search keyword & with the help of this we can predict the Future.

Suppose, If you search "Nokia N Series", that means either you may be planning to buy a Nokia N Series or you want to compare it with your own Cell Phone. With little bit of effort if you add up all this information, it would produce a pretty good notion of where the world was heading, of what was about to get hot & what is going out of style. You can call Internet, as Founder of Wired Magazine Mr.Battelle called it, "the database of intentions".
