Google Office In London, United Kingdom

In March 1999, the company moved its offices to Palo Alto, California, home to several other noted Silicon Valley technology startups. The next year, against Page and Brin's initial opposition toward an advertising-funded search engine, Google began selling advertisements associated with search keywords. In order to maintain an uncluttered page design and increase speed, advertisements were solely text-based. Keywords were sold based on a combination of price bids and click-throughs, with bidding starting at five cents per click. This model of selling keyword advertising was first pioneered by Goto.com, an Idealab spin-off created by Bill Gross. When the company changed names to Overture Services, it sued Google over alleged infringements of the company's pay-per-click and bidding patents. Overture Services would later be bought by Yahoo! and renamed Yahoo! Search Marketing. The case was then settled out of court, with Google agreeing to issue shares of common stock to Yahoo! in exchange for a perpetual license.
During this time, Google was granted a patent describing its PageRank mechanism. The patent was officially assigned to Stanford University and lists Lawrence Page as the inventor. In 2003, after outgrowing two other locations, the company leased its current office complex from Silicon Graphics at 1600 Amphitheatre Parkway in Mountain View, California. The complex has since come to be known as the Googleplex, a play on the word googolplex, the number one followed by a googol zeroes. Three years later, Google would buy the property from SGI for $319 million. By that time, the name "Google" had found its way into everyday language, causing the verb "google" to be added to the Merriam Webster Collegiate Dictionary and the Oxford English Dictionary, denoted as "to use the Google search engine to obtain information on the Internet."
