History of Google Search Engine

Hi,
Before delving deep into the anatomy and working of the Google search engine, let us know a little bit about the history of the marvelous search engine and how it came into being. The entity that rules the Internet today had modest beginnings (like all Silicon Valley start ups) in a garage in Menlo Park, California. The idea behind Google search engine has roots in the research project of company founders, Larry Page and Sergey Brin, when they were pursuing their PhD at Stanford University in circa 1996. They wrote an algorithm for web search (patented as 'PageRank' later), that weighed the importance of a page on the net, according to the number of links that were directed towards it. Instead of just searching for relevant keyword density like conventional web search engines, they gave importance to incoming links towards the page and the relevancy of those pages.

Google domain name finally got registered in 1997 and since then it has grown by leaps and bounds to become the premier web search engine on the Internet. Through acquisitions and innovations, Google has inculcated a lot more services to its web search features like YouTube, Google Earth and the recent launch of Google TV. Google offers advertising solutions through its Google AdSense and Google Adwords programs. Google's revenue is generated through advertisements placed by it on websites that submit themselves to their programs. This fact must have solved the prime curiosity of people about how does Google make money. After that brief overview of beginnings of the Google search engine, let us explore its inner workings.
