YouTube and selected creators earn 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 Music and YouTube Premium, subscription services respectively offering premium and ad-free music streaming, and ad-free access to all content, including exclusive content commissioned from notable personalities. As of February 2017, there were more than 400 hours of content uploaded to YouTube each minute, and one billion hours of content being watched on YouTube every day. As of August 2018, the website is ranked as the second-most popular site in the world, according to Alexa Internet, just behind Google. As of May 2019, more than 500 hours of video content are uploaded to YouTube every minute. Based on reported quarterly advertising revenue, YouTube is estimated to have US$15 billion in annual revenues.
The name "Google" originated from a misspelling of "googol", which refers to the number represented by a 1 followed by one-hundred zeros. Page and Brin write in their original paper on PageRank: "We chose our systems name, Google, because it is a common spelling of googol, or 10100 and fits well with our goal of building very large-scale search engines." 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." 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 is "Don't be evil". In October 2015, a related motto was adopted in the Alphabet corporate code of conduct by the phrase: "Do the right thing". The original motto was retained in the code of conduct of Google, now a subsidiary of Alphabet.
More InfoIn 2006, Google moved into about 300,000 square feet (27,900 m2) of office space in New York City, at 111 Eighth Avenue in Manhattan. The office was designed and built specially for Google, and houses its largest advertising sales team, which has been instrumental in securing large partnerships. In 2010, Google bought the building housing the headquarter, in a deal that valued the property at around $1.9 billion. In March 2018, Google's parent company Alphabet bought the nearby Chelsea Market building for $2.4 billion. The sale is touted as one of the most expensive real estate transactions for a single building in the history of New York. In November 2018, Google announced its plan to expand its New York City office to a capacity of 12,000 employees. The same December, it was announced that a $1 billion, 1,700,000-square-foot (160,000 m2) headquarters for Google would be built in Manhattan's Hudson Square neighborhood. Called Google Hudson Square, the new campus is projected to more than double the number of Google employees working in New York City.
More InfoIn 2010, Google Energy made its first investment in a renewable energy project, putting $38.8 million into two wind farms in North Dakota. The company announced the two locations will generate 169.5 megawatts of power, enough to supply 55,000 homes. In February 2010, the Federal Energy Regulatory Commission FERC granted Google an authorization to buy and sell energy at market rates. The corporation exercised this authorization in September 2013 when it announced it would purchase all the electricity produced by the not-yet-built 240-megawatt Happy Hereford wind farm.
More InfoIn 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 May 2011, the number of monthly unique visitors to Google surpassed one billion for the first time. By 2011, Google was handling approximately 3 billion searches per day. To handle this workload, Google built 11 data centers around the world with some several thousand servers in each. These data centers allowed Google to handle the ever changing workload more efficiently.
More InfoGoogle data centers are located in North and South America, Asia, and Europe. There is no official data on the number of servers in Google data centers; however, research and advisory firm Gartner estimated in a July 2016 report that Google at the time had 2.5 million servers. Traditionally, Google relied on parallel computing on commodity hardware like mainstream x86 computers (similar to home PCs) to keep costs per query low. In 2005, it started developing its own designs, which were only revealed in 2009.
