Google is an American multinational technology company that specializes in Internet-related services and products, which include online advertising technologies, search engine, cloud computing, software, and hardware. Google was founded in 1998 by Larry Page and Sergey Brin while they were Ph.D. students at Stanford UniversityCalifornia. 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 (IPO) 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 was appointed CEO of Google, replacing Larry Page, who became the CEO of Alphabet.
The company's rapid growth since incorporation has triggered a chain of products, acquisitions, and partnerships beyond Google's core search engine (Google Search). It offers services designed for work and productivity (Google Docs, Sheets, and Slides), email (Gmail/Inbox), scheduling and time management (Google Calendar), cloud storage (Google Drive), social networking (Google+), instant messaging and video chat (Google Allo/Duo/Hangouts), language translation (Google Translate), mapping and turn-by-turn navigation (Google Maps/Waze/Earth/Street View), video sharing (YouTube), note-taking (Google Keep), and photo organizing and editing (Google Photos). The company leads the development of the Android mobile operating system, the Google Chrome web browser, and Chrome OS, a lightweight operating system based on the Chrome browser. Google has moved increasingly into hardware; from 2010 to 2015, it partnered with major electronics manufacturers in the production of its Nexus devices, and in October 2016, it released multiple hardware products (including the Google Pixel smartphone, Home smart speaker, Wifi mesh wireless router, and Daydream View virtual reality headset). The new hardware chief, Rick Osterloh, stated: "a lot of the innovation that we want to do now ends up requiring controlling the end-to-end user experience". Google has also experimented with becoming an Internet carrier. In February 2010, it announced Google Fiber, a fiber-optic infrastructure that was installed in Kansas City; in April 2015, it launched Project Fi in the United States, combining Wi-Fi and cellular networks from different providers; and in 2016, it announced the Google Station initiative to make public Wi-Fi available around the world, with initial deployment in India.
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. Google is the most valuable brand in the world as of 2017; but has received significant criticism involving issues such as privacy concernstax avoidanceantitrustcensorship, and search neutrality. Google's mission statement, from the outset, was "to organize the world's information and make it universally accessible and useful", and its unofficial slogan was "Don't be evil". In October 2015, the motto was replaced in the Alphabet corporate code of conduct by the phrase "Do the right thing", while the original one was retained in the code of conduct of Google
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.

Advertising

For the 2006 fiscal year, the company reported $10.492 billion in total advertising revenues and only $112 million in licensing and other revenues. In 2011, 96% of Google's revenue was derived from its advertising programs. In addition to its own algorithms for understanding search requests, Google uses technology from the company DoubleClick, to project user interest and target advertising to the search context and the user history.

Software

Google develops the Android mobile operating system, as well as its smartwatchtelevisioncar, and Internet of things-enabled smart devices variations.
It also develops the Google Chrome web browser, and Chrome OS, an operating system based on Chrome.

Hardware

In January 2010, Google released Nexus One, the first Android phone under its own, "Nexus", brand. It spawned a number of phones and tablets under the "Nexus" branding until its eventual discontinuation in 2016, replaced by a new brand called, Pixel.
In 2011, the Chromebook was introduced, described as a "new kind of computer" running Chrome OS.
In July 2013, Google introduced the Chromecast dongle, that allows users to stream content from their smartphones to televisions.
In June 2014, Google announced Google Cardboard, a simple cardboard viewer that lets user place their smartphone in a special front compartment to view virtual reality (VR) media.
In April 2016, Recode reported that Google had hired Rick Osterloh, Motorola Mobility's former President, to head Google's new hardware division. In October 2016, Osterloh stated that "a lot of the innovation that we want to do now ends up requiring controlling the end-to-end user experience", and Google announced several hardware platforms:
  • The Pixel and Pixel XL smartphones with the Google Assistant, a next-generation contextual voice assistant, built-in.
  • Google Home, an Amazon Echo-like voice assistant placed in the house that can answer voice queries, play music, find information from apps (calendar, weather etc.), and control third-party smart home appliances (users can tell it to turn on the lights, for example).
  • Daydream View virtual reality headset that lets Android users with compatible Daydream-ready smartphones put their phones in the headset and enjoy VR content.
  • Google Wifi, a connected set of Wi-Fi routers to simplify and extend coverage of home Wi-Fi.

Internet services

In February 2010, Google announced the Google Fiber project, with experimental plans to build an ultra-high-speed broadband network for 50,000 to 500,000 customers in one or more American cities. Following Google's corporate restructure to make Alphabet Inc. its parent company, Google Fiber was moved to Alphabet's Access division.
In April 2015, Google announced Project Fi, a mobile virtual network operator, that combines Wi-Fi and cellular networks from different telecommunication providers in an effort to enable seamless connectivity and fast Internet signal.
In September 2016, Google began its Google Station initiative, a project for public Wi-Fi at railway stations in India. Caesar Sengupta, VP for Google's next billion users, told The Verge that 15,000 people get online for the first time thanks to Google Station and that 3.5 million people use the service every month. The expansion meant that Google was looking for partners around the world to further develop the initiative, which promised "high-quality, secure, easily accessible Wi-Fi". By December, Google Station had been deployed at 100 railway stations, and in February, Google announced its intention to expand beyond railway stations, with a plan to bring citywide Wi-Fi to Pune.

On January 28, 2013, Twitter acquired Crashlytics in order to build out its mobile developer products.
Twitter (/ˈtwɪtÉ™r/) is an online news and social networking service on which users post and interact with messages known as "tweets". Tweets were originally restricted to 140 characters, but on November 7, 2017, this limit was doubled for all languages except Japanese, Korean, and Chinese. Registered users can post tweets, but those who are unregistered can only read them. Users access Twitter through its website interface, through Short Message Service (SMS) or mobile-device application software ("app"). Twitter, Inc. is based in San Francisco, California, and has more than 25 offices around the world.
Twitter was created in March 2006 by Jack DorseyNoah GlassBiz Stone, and Evan Williams and launched in July of that year. The service rapidly gained worldwide popularity. In 2012, more than 100 million users posted 340 million tweets a day, and the service handled an average of 1.6 billion search queries per day. In 2013, it was one of the ten most-visited websites and has been described as "the SMS of the Internet". As of 2016, Twitter had more than 319 million monthly active users. On the day of the 2016 U.S. presidential election, Twitter proved to be the largest source of breaking news, with 40 million election-related tweets sent by 10 p.m. (Eastern Time) that day.
On April 18, 2013, Twitter launched a music app called Twitter Music for the iPhone. On August 28, 2013, Twitter acquired Trendrr, followed by the acquisition of MoPub on September 9, 2013. As of September 2013, the company's data showed that 200 million users send over 400 million tweets daily, with nearly 60% of tweets sent from mobile devices. On June 4, 2014, Twitter announced that it will acquire Namo Media, a technology firm specializing in "native advertising" for mobile devices. On June 19, 2014, Twitter announced that it has reached an undisclosed deal to buy SnappyTV, a service that helps edit and share video from television broadcasts. The company was helping broadcasters and rights holders to share video content both organically across social and via Twitter's Amplify program. In July 2014, Twitter announced that it intends to buy a young company called CardSpring for an undisclosed sum. CardSpring enables retailers to offer online shoppers coupons that they can automatically sync to their credit cards in order to receive discounts when they shop in physical stores. On July 31, 2014, Twitter announced that it has acquired a small password-security startup called Mitro. On October 29, 2014, Twitter announced a new partnership with IBM. The partnership is intended to help businesses use Twitter data to understand their customers, businesses and other trends.
Logo

July 15, 2006 – September 14, 2010

September 14, 2010 – June 5, 2012
Twitter has become internationally identifiable by its signature bird logo, or the Twitter Bird. The original logo, which was simply the word "Twitter", was in use from its launch in March 2006 until September 2010. A slightly modified version with "Larry the Bird" next to the old logo succeeded the first style when the website underwent its first redesign. A tweet from an employee that works on the company's platform and API discussed the evolution of the "Larry the Bird" logo with Twitter's creative director and it was revealed that it was named after Larry Birdof the NBA's Boston Celtics fame. This detail had been confirmed when the Boston Celtics' director of interactive media asked Twitter co-founder Biz Stone about it in August 2011.

June 5, 2012 – present
In 2012, Twitter unveiled its third logo redesign, replacing Larry the Bird with an updated icon simply named as the "Twitter Bird," as seen to the right. As of this logo revision, the word "Twitter" and the lowercase letter "t" are no longer used, with the bird becoming the sole symbol for the company's branding. According to Douglas Bowman, designer of Twitter, the new logo resembles a mountain bluebird.

Tweets

Tweets are publicly visible by default, but senders can restrict message delivery to just their followers. Users can tweet via the Twitter website, compatible external applications (such as for smartphones), or by Short Message Service (SMS) available in certain countries. Users may subscribe to other users' tweets—this is known as "following" and subscribers are known as "followers" or "tweeps", a portmanteau of Twitter and peeps. Individual tweets can be forwarded by other users to their own feed, a process known as a "retweet". Users can also "like" (formerly "favorite") individual tweets. Twitter allows users to update their profile via their mobile phone either by text messaging or by apps released for certain smartphones and tablets. Twitter has been compared to a web-based Internet Relay Chat (IRC) client. In a 2009 Time essay, technology author Steven Johnson described the basic mechanics of Twitter as "remarkably simple":
As a social network, Twitter revolves around the principle of followers. When you choose to follow another Twitter user, that user's tweets appear in reverse chronological order on your main Twitter page. If you follow 20 people, you'll see a mix of tweets scrolling down the page: breakfast-cereal updates, interesting new links, music recommendations, even musings on the future of education.

YouTube is an American video-sharing website headquartered in San Bruno, California. The service was created by three former PayPal employees—Chad HurleySteve Chen, and Jawed Karim—in February 2005. Google bought the site in November 2006 for US$1.65 billion; YouTube now operates as one of Google's subsidiaries.
YouTube allows users to upload, view, rate, share, add to favorites, report, comment on videos, and subscribe to other users. It offers a wide variety of user-generated and corporate media videos. Available content includes video clipsTV show clips, music videosshortand documentary films, audio recordings, movie trailerslive streams, and other content such as video blogging, short original videos, and educational videos. Most of the content on YouTube is uploaded by individuals, but media corporations including CBS, the BBCVevo, and Hulu offer some of their material via YouTube as part of the YouTube partnership program. Unregistered users can only watch videos on the site, while registered users are permitted to upload an unlimited number of videos and add comments to videos. Videos deemed potentially inappropriate are available only to registered users affirming themselves to be at least 18 years old.
YouTube earns advertising revenue from Google AdSense, a program which targets ads according to site content and audience. The vast majority of its videos are free to view, but there are exceptions, including subscription-based premium channels, film rentals, as well as YouTube Red, a subscription service offering ad-free access to the website and access to exclusive content made in partnership with existing users. As of February 2017, there are more than 400 hours of content uploaded to YouTube each minute, and one billion hours of content are watched on YouTube every day. As of August 2017, the website is ranked as the second-most popular site in the world by Alexa Internet, a web traffic analysis company.

Company history

From left to right: Chad HurleySteve Chen and Jawed Karim
YouTube was founded by Chad HurleySteve Chen and Jawed Karim, who were all early employees of PayPal. Hurley had studied design at Indiana University of Pennsylvania, and Chen and Karim studied computer science together at the University of Illinois at Urbana-Champaign. According to a story that has often been repeated in the media, Hurley and Chen developed the idea for YouTube during the early months of 2005, after they had experienced difficulty sharing videos that had been shot at a dinner party at Chen's apartment in San Francisco. Karim did not attend the party and denied that it had occurred, but Chen commented that the idea that YouTube was founded after a dinner party "was probably very strengthened by marketing ideas around creating a story that was very digestible".
Karim said the inspiration for YouTube first came from Janet Jackson's role in the 2004 Super Bowl incident, when her breast was exposed during her performance, and later from the 2004 Indian Ocean tsunami. Karim could not easily find video clips of either event online, which led to the idea of a video sharing site Hurley and Chen said that the original idea for YouTube was a video version of an online dating service, and had been influenced by the website Hot or Not.

YouTube began as a venture capital-funded technology startup, primarily from an $11.5 million investment by Sequoia Capital between November 2005 and April 2006. YouTube's early headquarters were situated above a pizzeria and Japanese restaurant in San Mateo, California. The domain name www.youtube.com was activated on February 14, 2005, and the website was developed over the subsequent months. The first YouTube video, titled Me at the zoo, shows co-founder Jawed Karim at the San Diego Zoo. The video was uploaded on April 23, 2005, and can still be viewed on the site. YouTube offered the public a beta test of the site in May 2005. The first video to reach one million views was a Nike advertisement featuring Ronaldinho in November 2005. Following a $3.5 million investment from Sequoia Capital in November, the site launched officially on December 15, 2005, by which time the site was receiving 8 million views a day. The site grew rapidly and, in July 2006, the company announced that more than 65,000 new videos were being uploaded every day, and that the site was receiving 100 million video views per day. According to data published by market research company comScore, YouTube is the dominant provider of online video in the United States, with a market share of around 43% and more than 14 billion views of videos in May 2010.
In May 2011, 48 hours of new videos were uploaded to the site every minute, which increased to 60 hours every minute in January 2012, 100 hours every minute in May 2013, 300 hours every minute in November 2014, and 400 hours every minute in February 2017. The site has 800 million unique users a month. It is estimated that in 2007 YouTube consumed as much bandwidth as the entire Internet in 2000. According to third-party web analytics providers, Alexa and SimilarWeb, YouTube is the second-most visited website in the world, as of December 2016; SimilarWeb also lists YouTube as the top TV and video website globally, attracting more than 15 billion visitors per month.
The choice of the name www.youtube.com led to problems for a similarly named website, www.utube.com. The site's owner, Universal Tube & Rollform Equipment, filed a lawsuit against YouTube in November 2006 after being regularly overloaded by people looking for YouTube. Universal Tube has since changed the name of its website to www.utubeonline.com. In October 2006, Google Inc. announced that it had acquired YouTube for $1.65 billion in Google stock, and the deal was finalized on November 13, 2006.

3D videos

In a video posted on July 21, 2009, YouTube software engineer Peter Bradshaw announced that YouTube users can now upload 3D videos. The videos can be viewed in several different ways, including the common anaglyph (cyan/red lens) method which utilizes glasses worn by the viewer to achieve the 3D effect. The YouTube Flash player can display stereoscopic content interleaved in rows, columns or a checkerboard pattern, side-by-side or anaglyph using a red/cyan, green/magenta or blue/yellow combination. In May 2011, an HTML5 version of the YouTube player began supporting side-by-side 3D footage that is compatible with Nvidia 3D Vision.

360° videos

In January 2015, Google announced that 360° videos would be natively supported on YouTube. On March 13, 2015, YouTube enabled 360° videos which can be viewed from Google Cardboard, a virtual reality system. YouTube 360 can also be viewed from all other virtual reality headsets. Live streaming of 360° video at up to 4K resolution is also supported.

Community

On September 13, 2016, YouTube launched a public beta of Community, a social media-based feature that allows users to post text, images (including GIFs), live videos and others in a separate "Community" tab on their channel. Prior to the release, several creators had been consulted to suggest tools Community could incorporate that they would find useful; these YouTubers included VlogbrothersAsapScienceLilly SinghThe Game TheoristsKarminThe Key of Awesome, The Kloons, Peter HollensRosianna Halse RojasSam Tsui, Threadbanger and Vsauce3.
