Google duo and all about Google

Google was co-founded by Larry Page and Sergey Brin while they were students at Stanford University and the company was first incorporated as a privately held company on September 7, 1998. Google's initial public offering took place on August 19, 2004, raising $1.67 billion, making it worth $23 billion. Through a series of new product developments, acquisitions and partnerships, the company has expanded its initial search and advertising business into other areas, including web-based email, online mapping, office productivity, and video sharing, among others.

Google began in January 1996, as a research project by Larry Page and Sergey Brin, two Ph.D. students at Stanford University, California. They hypothesized that a search engine that analyzed the relationships between websites would produce better ranking of results than existing techniques, which ranked results according to the number of times the search term appeared on a page. Their search engine was originally nicknamed "BackRub" because the system checked backlinks to estimate a site's importance. A small search engine called Rankdex was already exploring a similar strategy. Convinced that the pages with the most links to them from other highly relevant web pages must be the most relevant pages associated with the search, Page and Brin tested their thesis as part of their studies, and laid the foundation for their search engine. Originally, the search engine used the Stanford University website with the domain google.stanford.edu. The domain google.com was registered on September 15, 1997, and the company was incorporated as Google Inc. on September 7, 1998 at a friend's garage in Menlo Park, California. The total initial investment raised for the new company eventually amounted to almost $1.1 million, including a $100,000 check by Andy Bechtolsheim, one of the founders of Sun Microsystems.

The founders originally were keen to acquire the domain "Googol.com". It was registered to a local Silicon Valley engineer (Tim Beauchamp) who was using it as a site for math and astronomy. He did not want to relinquish the domain at the time.

In March 1999, the company moved into offices in Palo Alto, home to several other noted Silicon Valley technology startups. After quickly outgrowing two other sites, the company leased a complex of buildings in Mountain View at 1600 Amphitheatre Parkway from Silicon Graphics (SGI) in 2003. The company has remained at this location ever since, and the complex has since come to be known as the Googleplex (a play on the word googolplex, a 1 followed by a googol zeros). In 2006, Google bought the property from SGI for $319 million.

The Google search engine attracted a loyal following among the growing number of Internet users, who liked its simple design and usability. It should also be noted that one reason for the simplistic design was due to the lack of HTML programming knowledge held by the Google founders. In 2000, Google began selling advertisements associated with search keywords. The ads were text-based to maintain an uncluttered page design and to maximize page loading speed.Keywords were sold based on a combination of price bid and clickthroughs, with bidding starting at $.05 per click. This model of selling keyword advertising was pioneered by Goto.com (later renamed Overture Services, before being acquired by Yahoo! and rebranded as Yahoo! Search Marketing). While many of its dot-com rivals failed in the new Internet marketplace, Google quietly rose in stature while generating revenue.

The name "Google" originated from a misspelling of "googol", which refers to 10100 (the number represented by a 1 followed by one-hundred zeros). Having found its way increasingly into everyday language, the verb "google", was added to the Merriam Webster Collegiate Dictionary and the Oxford English Dictionary in 2006, meaning "to use the Google search engine to obtain information on the Internet."

A patent describing part of Google's ranking mechanism (PageRank) was granted on September 4, 2001. The patent was officially assigned to Stanford University and lists Lawrence Page as the inventor.

While the company's primary business interest is in the web content arena, Google has begun experimenting with other markets, such as radio and print publications. On January 17, 2006, Google announced that its purchase of a radio advertising company "dMarc", which provides an automated system that allows companies to advertise on the radio. This will allow Google to combine two niche advertising media—the Internet and radio—with Google's ability to laser-focus on the tastes of consumers. Google has also begun an experiment in selling advertisements from its advertisers in offline newspapers and magazines, with select advertisements in the Chicago Sun-Times. They have been filling unsold space in the newspaper that would have normally been used for in-house advertisements.

Google was added to the S&P 500 index on March 30, 2006. It replaced Burlington Resources, a major oil producer based in Houston which was acquired by ConocoPhillips.
