In 1995, Larry Page and Sergey Brin met at Stanford University. By 1996, the two computer science graduate students were collaborating on a search engine project originally nicknamed BackRub. At the time, conventional search engines ranked results primarily by how frequently a search term appeared on a web page. Page and Brin had a fundamentally different insight: what if the relevance of a webpage was determined by how many other pages linked to it?
They called this core technology PageRank, transforming citations and web links into votes of credibility. Soon after, they renamed their fledgling engine Google—a play on googol, the mathematical term representing the number 1 followed by 100 zeros, reflecting their mission to organize an apparently infinite amount of information.
The Garage and the Launch (1998)
On September 4, 1998, Google officially incorporated as a private company. Armed with an initial $100,000 investment from Sun Microsystems co-founder Andy Bechtolsheim, the founders moved their operations out of their dorm rooms and into the Menlo Park garage of Susan Wojcicki (who would later become CEO of YouTube). Unlike the cluttered, portal-heavy homepages of early web rivals like Yahoo! and Excite, Google featured a stark, clean white page with a single search box. It loaded fast, delivered uncannily accurate results, and quickly built a cult following purely through word-of-mouth. By 2000, Google had indexed over one billion URLs, officially becoming the world’s largest search engine.
Building the Engine: Advertising and Innovation
Search alone, however, needed a sustainable business model. In late 2000, Google launched AdWords (now Google Ads), followed in 2003 by AdSense. Instead of intrusive pop-ups, Google paired search queries with text-based, keyword-targeted advertising. This pay-per-click model unlocked massive revenues, aligning advertising utility directly with user intent.
In 2004, Google made two historic moves:

April 1, 2004: The launch of Gmail, offering a staggering 1 GB of free storage—nearly 500 times what competitors offered—which many initially mistook for an April Fools’ prank.
August 19, 2004: An initial public offering (IPO) on Wall Street that raised $1.67 billion, valuing the company at over $23 billion.

Beyond the Search Box: Mobile, Video, and Cloud
Over the following decade, Google evolved from a search provider into an all-encompassing digital ecosystem:
Android (2005/2008): Google acquired a small mobile startup in 2005, releasing the open-source Android OS in 2008. Today, it powers the majority of global smartphones.
YouTube (2006): The $1.65 billion acquisition cemented Google as the dominant global hub for digital video and creator culture.
Google Chrome (2008): Engineered from scratch for speed and web applications, Chrome rapidly grew to become the world’s dominant web browser.
Google Workspace & Cloud: Tools like Docs, Sheets, and Drive pioneered real-time web collaboration, while Google Cloud expanded enterprise computing infrastructure worldwide.
Alphabet and the AI Frontier
In 2015, Google restructured under a holding company called Alphabet Inc., separating core web businesses from speculative “Other Bets” such as Waymo (autonomous vehicles) and Verily (life sciences). Sundar Pichai stepped up as Google’s CEO, later assuming the role of Alphabet CEO as well.
In 2016, Pichai announced Google’s strategic shift from a “mobile-first” to an “AI-first” company. That commitment culminated in groundbreaking research, most notably the 2017 introduction of the Transformer architecture—the fundamental foundation behind nearly all modern generative artificial intelligence.
Today, with multimodal models like Gemini deeply integrated across search, workspace, and mobile computing, Google’s original founding mission remains intact: to organize the world’s information and make it universally accessible and useful.
