This evergreen history article uses authoritative archives and official records. Exact dates are used when documented; gradual inventions and rollouts are described as periods rather than being assigned a misleading single birthday.
Quick facts
- Larry Page and Sergey Brin met at Stanford University in California in 1995.
- Their early search system was called BackRub because it analysed links pointing to web pages.
- Google was incorporated in 1998 after receiving an early investment from Sun Microsystems co-founder Andy Bechtolsheim.
- The company moved from search into advertising, email, maps, video, mobile operating systems, browsers, cloud services and AI.
- Alphabet became Google’s parent company in 2015.
The search problem of the 1990s
The early Web grew faster than human-edited directories could organise it. Search engines existed, but many ranked pages mainly by how often a query term appeared. This made results vulnerable to repetition and did not reliably identify authority.
At Stanford University, doctoral students Larry Page and Sergey Brin explored whether links could act like academic citations. A page receiving links from important pages might itself be important. Their research combined web crawling, link analysis and mathematical ranking.
BackRub and PageRank
Page began examining the Web’s link structure in 1996. Brin joined the project, and the system became known as BackRub. Its ranking method was called PageRank, a name linked both to web pages and Larry Page. The research system ran on Stanford computers and rapidly attracted users because its results often felt more relevant than those of competitors.
The project also showed a larger idea: the Web was not merely a collection of documents. Its links formed a graph that could reveal relationships, reputation and authority.
The Google name and company formation
BackRub was renamed Google, a play on “googol,” the mathematical term for 1 followed by 100 zeros. The name reflected the ambition to organise enormous amounts of information.
In August 1998, Andy Bechtolsheim wrote a cheque for $100,000 to the not-yet-fully-formed company. Google Inc. was incorporated soon afterwards. The founders worked from a garage in Menlo Park, California, rented from Susan Wojcicki, who later became a senior Google executive and chief executive of YouTube.
Search quality and a new advertising model
Google’s uncluttered home page, fast response and improving relevance helped it grow. The company developed text advertising linked to search intent. AdWords, launched in 2000, allowed businesses to place ads associated with keywords. AdSense later extended contextual advertising to third-party websites.
This model funded free services and became one of the most influential business systems on the commercial Web. It also created long-running debates about tracking, competition, market power and the relationship between useful search and advertising incentives.
From search engine to product ecosystem
Google expanded rapidly. Gmail launched in 2004 with unusually large storage for the period. Google Maps followed in 2005. The company acquired YouTube in 2006, giving it a leading position in online video. Chrome arrived in 2008 and became a major web browser.
Google acquired Android Inc. in 2005 and backed an open mobile operating system ecosystem. The first commercial Android phone appeared in 2008. Android helped Google services reach billions of mobile devices and intensified competition with Apple’s iPhone platform.
Cloud computing, infrastructure and knowledge
Google built enormous data centres, distributed storage systems and software infrastructure to operate search at global scale. Research papers describing technologies such as the Google File System, MapReduce and Bigtable influenced modern distributed computing.
Google Cloud turned parts of that expertise into services for businesses and developers. The company also invested in translation, digital books, academic search, Earth imagery, productivity software and knowledge graphs.
Alphabet and the AI transition
In 2015, Google created Alphabet Inc. as a parent holding company. Google remained the largest business, while experimental ventures could operate in separate units. The structure reflected the company’s expansion into areas such as health technology, autonomous driving and long-term research.
Machine learning had already improved search, advertising, speech and translation. Google’s acquisition of DeepMind in 2014 strengthened its research position. Transformer research published by Google researchers in 2017 became foundational to modern large language models. The company later developed the Gemini model family and integrated generative AI into search, productivity, cloud and developer products.
Influence and controversy
Google made information easier to locate and created products used in education, business, navigation and entertainment. At the same time, regulators and critics have examined privacy, advertising practices, app-store rules, search distribution agreements, content moderation and competition.
Its history therefore combines technical innovation with questions about how a company that organises information should be governed. Search results can shape attention, while mobile platforms, browsers and advertising systems influence how digital markets operate.
Common misconceptions
- Google was not the first search engine; it entered an already active market.
- PageRank was important, but modern Google ranking uses many systems rather than one formula.
- Google and Alphabet are not identical legal concepts: Alphabet is the parent company, while Google is its largest operating business.
- The company did not begin in the famous garage; the research project began at Stanford before the founders moved into the garage.
