"Google" What is this fellow ?

 Google is an American multinational technology company specializing in Internet-related services and products. These include online advertising technologies, search, cloud computing, software, and hardware.
Google was founded in 1996 by Larry Page and Sergey Brin while they were Ph.D. students at Stanford University, in California. Together, they own about 14 percent of its shares and control 56 percent of the stockholder voting power through supervoting stock. They incorporated Google as a privately held company on September 4, 1998. An initial public offering  took place on August 19, 2004, and Google moved to its new headquarters in Mountain View, California, nicknamed the Googleplex.
In August 2015, Google announced plans to reorganize its various interests as a conglomerate called Alphabet Inc. Google, Alphabet's leading subsidiary, will continue to be the umbrella company for Alphabet's Internet interests. Upon completion of the restructure, Sundar Pichai became CEO of Google, replacing Larry Page, who became CEO of Alphabet. and in October 2016, it launched multiple hardware products . In October 2015, the motto was replaced in the Alphabet corporate code of conduct by the phrase: "Do the right thing".
Google's commitment to such robust idealism has been increasingly called into doubt due to a number of the firm's actions and behaviours which appear to contradict this.
History
Google began in January 1996 as a research project by Larry Page and Sergey Brin when they were both PhD students at Stanford University in Stanford, California.
While conventional search engines ranked results by counting how many times the search terms appeared on the page, the two theorized about a better system that analyzed the relationships among websites. They called this new technology PageRank; it determined a website's relevance by the number of pages, and the importance of those pages, that linked back to the original site.
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 1 followed by 100 zeros, which was picked to signify that the search engine was intended to provide large quantities of information. Originally, Google ran under Stanford University's website, with the domains google.stanford.edu and z.stanford.edu.
The domain name for Google was registered on September 15, 1997, and the company was incorporated on September 4, 1998. It was based in the garage of a friend  invested $250,000, but other sources have reported a $100,000 level. with major investors including the venture capital firms Kleiner Perkins Caufield & Byers and Sequoia Capital.
Google's initial public offering  took place five years later, on August 19, 2004. At that time Larry Page, Sergey Brin, and Eric Schmidt agreed to work together at Google for 20 years, until the year 2024.

At IPO, the company offered 19,605,052 shares at a price of $85 per share. Shares were sold in an online auction format using a system built by Morgan Stanley and Credit Suisse, underwriters for the deal. The sale of $1.67 bn  gave Google a market capitalization of more than $23bn. By January 2014, its market capitalization had grown to $397bn. The vast majority of the 271 million shares remained under the control of Google, and many Google employees became instant paper millionaires. Yahoo!, a competitor of Google's, also benefitted because it owned 8.4 million shares of Google before the IPO took place.
There were concerns that Google's IPO would lead to changes in company culture. Reasons ranged from shareholder pressure for employee benefit reductions to the fact that many company executives would become instant paper millionaires. As a reply to this concern, co-founders Brin and Page promised in a report to potential investors that the IPO would not change the company's culture. In 2005, articles in The New York Times and other sources began suggesting that Google had lost its anti-corporate, no evil philosophy. In an effort to maintain the company's unique culture, Google designated a Chief Culture Officer, who also serves as the Director of Human Resources. The purpose of the Chief Culture Officer is to develop and maintain the culture and work on ways to keep true to the core values that the company was founded on: a flat organization with a collaborative environment. Google has also faced allegations of sexism and ageism from former employees. In 2013, a class action against several Silicon Valley companies, including Google, was filed for alleged "no cold call" agreements which restrained the recruitment of high-tech employees.
The stock performed well after the IPO, with shares hitting $350 for the first time on October 31, 2007, primarily because of strong sales and earnings in the online advertising market. The surge in stock price was fueled mainly by individual investors, as opposed to large institutional investors and mutual funds. The company is listed on the NASDAQ stock exchange under the ticker symbols GOOGL and GOOG, and on the Frankfurt Stock Exchange under the ticker symbol GGQ1. These ticker symbols now refer to Alphabet Inc., Google's holding company, since the fourth quarter of 2015.
Growth
In March 1999, the company moved its offices to Palo Alto, California, which is home to several prominent Silicon Valley technology start-ups. The next year, against Page and Brin's initial opposition toward an advertising-funded search engine, Google began selling advertisements associated with search keywords. 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; Google agreed to issue shares of common stock to Yahoo! in exchange for a perpetual license.
In 2001, Google received a patent for 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 an office complex from Silicon Graphics, at 1600 Amphitheatre Parkway in Mountain View, California. The complex became known as the Googleplex, a play on the word googolplex, the number one followed by a googol zeroes. The Googleplex interiors were designed by Clive Wilkinson Architects. Three years later, Google bought 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". The first use of "Google" as a verb in pop culture happened on the tV series Buffy the Vampire Slayer, in 2002.
In 2005, The Washington Post reported on a 700 percent increase in third-quarter profit for Google, largely thanks to large companies shifting their advertising strategies from newspapers, magazines, and television to the Internet.
In January 2008, all the data that passed through Google's MapReduce software component had an aggregated size of 20 petabytes per day.
In 2009, a CNN report about top political searches of 2009 noted that "more than a billion searches" are being typed into Google on a daily basis.
In May 2011, the number of monthly unique visitors to Google surpassed one billion for the first time, an 8.4 percent increase from May 2010 .
2012 marked the first year that Google generated $50 billion in annual revenue, topping 2011's $38 billion generated. Then-CEO Larry Page commented in January 2013: "We ended 2012 with a strong quarter ... Revenues were up 36% year-on-year, and 8% quarter-on-quarter. And we hit $50 billion in revenues for the first time last year – not a bad achievement in just a decade and a half."
2013 onward
Google announced the launch of a new company, called Calico, on September 19, 2013, to be led by Apple, Inc. chairman Arthur Levinson. In the official public statement, Page explained that the "health and well-being" company would focus on "the challenge of ageing and associated diseases".
Google celebrated its 15-year anniversary on September 27, 2013, and in 2016 it celebrated its 18th birthday with an animated Doodle shown on web browsers around the world. although it has used other dates for its official birthday. The reason for the choice of September 27 remains unclear, and a dispute with rival search engine Yahoo! Search in 2005 has been suggested as the cause.
The Alliance for Affordable Internet  was launched in October 2013; Google is part of the coalition of public and private organisations that also includes Facebook, Intel, and Microsoft. Led by Sir Tim Berners-Lee, the A4AI seeks to make Internet access more affordable so that access is broadened in the developing world, where only 31% of people are online. Google will help to decrease Internet access prices so they fall below the UN Broadband Commission's worldwide target of 5% of monthly income.
The corporation's consolidated revenue for the third quarter of 2013 was reported in mid-October 2013 as $14.89 billion, a 12 percent increase compared to the previous quarter. Google's Internet business was responsible for $10.8 billion of this total, with an increase in the number of users' clicks on advertisements.
In November 2013, Google announced plans for a new 1-million-sq-ft  office in London, which was due to open in 2016. The new premises, able to accommodate 4,500 employees, has been identified as one of the biggest ever commercial property acquisitions in Britain.
According to Interbrand's annual Best Global Brands report, Google has been the second most valuable brand in the world  in 2013, 2014, 2015, and 2016, with a valuation of $133 billion.
In September 2015, Google engineering manager Rachel Potvin revealed details about Google's software code at an engineering conference. She revealed that the entire Google codebase, which spans every single service it develops, consists of over 2 billion lines of code. All that code is stored on a code repository available to all 25,000 Google engineers, and the code is regularly copied and updated on 10 Google data centers. To keep control, Potvin said Google has built its own "version control system", called "Piper", and that "when you start a new project, you have a wealth of libraries already available to you. Almost everything has already been done." Engineers can make a single code change and deploy it on all services at the same time. The only major exceptions are that the PageRank search results algorithm is stored separately with only specific employee access, and the code for the Android operating system and the Google Chrome browser are also stored separately, as they don't run on the Internet. The "Piper" system spans 85 TB of data. Google engineers make 25,000 changes to the code each day, and on a weekly basis change approximately 15 million lines of code across 250,000 files. With that much code, automated bots have to help. Potvin reported, "You need to make a concerted effort to maintain code health. And this is not just humans maintaining code health, but robots too.” Bots aren't writing code, but generating a lot of the data and configuration files needed to run the company’s software. "Not only is the size of the repository increasing," Potvin explained, "but the rate of change is also increasing. This is an exponential curve."
As of October 2016, Google operates 70 offices in more than 40 countries.
Alexa, a company that monitors commercial web traffic, lists Google.com as the most visited website in the world. Several other Google services also figure in the top 100 most visited websites, including YouTube and Blogger.
