Google is an American multinational technology company specializing in Internet-related services and products. These include online advertising technologies, search, cloud computing, and software. Most of its profits are derived from AdWords, an online advertising service that places advertising near the list of search results.
Google was founded by Larry Page and Sergey Brin while they were Ph.D. students at Stanford University. 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 followed on August 19, 2004. Its 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 2004, Google moved to its new headquarters in Mountain View, California, nicknamed the Googleplex. In August 2015, Google announced plans to reorganize its interests as a holding company called Alphabet Inc. When this restructuring took place on October 2, 2015, Google became Alphabet's leading subsidiary, as well as the parent for Google's Internet interests.
Rapid growth since incorporation has triggered a chain of products, acquisitions and partnerships beyond Google's core search engine (Google Search). It offers online productivity software (Google Docs) including email (Gmail), a cloud storage service (Google Drive) and a social networking service (Google+). Desktop products include applications for web browsing (Google Chrome), organizing and editing photos (Google Photos), and instant messaging and video chat (Hangouts). The company leads the development of the Android mobile operating system and the browser-only Chrome OS for a class of netbooks known as Chromebooks and desktop PCs known as Chromeboxes. Google has moved increasingly into communications hardware, partnering with major electronics manufacturers in the production of its "high-quality low-cost" Nexus devices. In 2012, a fiber-optic infrastructure was installed in Kansas City to facilitate a Google Fiber broadband service.
The corporation has been estimated to run more than one million servers in data centers around the world (as of 2007). It processes over one billion search requests and about 24 petabytes of user-generated data each day (as of 2009). In December 2013, Alexa listed google.com as the most visited website in the world. Numerous Google sites in other languages figure in the top one hundred, as do several other Google-owned sites such as YouTube and Blogger. Its market dominance has led to prominent media coverage, including criticism of the company over issues such as aggressive tax avoidance, search neutrality, copyright, censorship, and privacy.
Yahoo Inc. (often styled as YAHOO!) is an American multinational technology company headquartered in Sunnyvale, California. It is globally known for its Web portal, search engine Yahoo! Search, and related services, including Yahoo! Directory, Yahoo! Mail, Yahoo! News, Yahoo! Finance, Yahoo! Groups, Yahoo! Answers, advertising, online mapping, video sharing, fantasy sports and its social media website. It is one of the most popular sites in the United States. According to third-party web analytics providers, Alexa and SimilarWeb, Yahoo! is the highest-read news and media website, with over 7 billion readers per month, being the fourth most visited website globally, as of June 2015. According to news sources, roughly 700 million people visit Yahoo websites every month. Yahoo itself claims it attracts "more than half a billion consumers every month in more than 30 languages."
Yahoo was founded by Jerry Yang and David Filo in January 1994 and was incorporated on March 2, 1995. Marissa Mayer, a former Google executive, serves as CEO and President of the company.
In January 2015, the company announced it planned to spin-off its stake in Alibaba Group in a separately listed company. In December 2015 it reversed this decision, opting instead to spin-off its internet business as a separate company.
