Google began in March 1996 as a research project by Larry Page and Sergey Brin, Ph.D. students at Stanford working on the Stanford Digital Library Project (SDLP). The SDLP's goal was “to develop the enabling technologies for a single, integrated and universal digital library" and was funded through the National Science Foundation among other federal agencies. In search for a dissertation theme, Page considered—among other things—exploring the mathematical properties of the World Wide Web, understanding its link structure as a huge graph. His supervisor Terry Winograd encouraged him to pick this idea (which Page later recalled as "the best advice I ever got") and Page focused on the problem of finding out which web pages link to a given page, considering the number and nature of such back links to be valuable information about that page (with the role of citations in academic publishing in mind). In his research project, nicknamed "BackRub", he was soon joined by Sergey Brin, a fellow Stanford Ph.D. student supported by a National Science Foundation Graduate Fellowship. Brin was already a close friend, whom Page had first met in the summer of 1995 in a group of potential new students which Brin had volunteered to show around the campus. Page's web crawler began exploring the web in March 1996, setting out from Page's own Stanford home page as its only starting point. To convert the backlink data that it gathered into a measure of importance for a given web page, Brin and Page developed the PageRank algorithm. Analysing BackRub's output—which, for a given URL, consisted of a list of backlinks ranked by importance—it occurred to them that a search engine based on PageRank would produce better results than existing techniques (existing search engines at the time essentially ranked results according to how many times the search term appeared on a page). Page and Brin originally nicknamed their new search engine "BackRub", because the system checked backlinks to estimate the importance of a site. Eventually, they changed the name to Google, originating from a misspelling of the word "googol", the number one followed by one hundred zeros, which was picked to signify that the search engine wants to provide large quantities of information for people. The domain name for Google was registered on September 15, 1997, and the company was incorporated on September 4, 1998. It was based in a friend's garage in Menlo Park, California. Craig Silverstein, a fellow PhD student at Stanford, was hired as the first employee.
There are lot of products in the Google’s Portfolio some of which are created by Google such as the Google Search Engine and many of them are added due to the acquisitions from 1998. Some of the important products are mentioned in this slide. As per survey done for August US search, Google is ahead with 11.1 billion searches compared with Search of 2.8 Billion of Yahoo and 2.5 Billion of Microsoft. Google have made such a impact that now we don’t say that we are going to search on internet but we say as Let’s Google it. Google paid around $700 Million for the ITA Software which makes software that aggregate online flight and ticketing information from the airline and $125 Million for Zagat for Local information of restaurants. After this acquisition of Google, now we can use the Google flight search, plan our travel and check the restaurant with higher rating which can be found by the android application provided by Google. Everyone knows about the usage of Google maps having share of 67.1% in US market share in August. It helps us the pinpoint the exact location, distance between two places and also gives the direction/path in case we want to travel. Google spent $12.5 Billion to acquire Motorola Mobility (maker of Android smartphones). In mobile software, Android have the market share of 43.5%. Google have launched it’s own browser Chroma which have taken the US...
