Google's 27th Birthday: How a Spelling Mistake Gave Birth to the World’s Biggest Search Giant

Google’s 27th Birthday is a reminder of how innovation and serendipity shaped one of the world’s most powerful tech empires. On September 27, 2025, billions around the globe celebrate the legacy and impact of the search giant, whose name itself holds an extraordinary story rooted in a simple mistake.

The Birth of Google’s 27th Birthday

Google’s journey started in a Menlo Park garage in 1998, when Larry Page and Sergey Brin, two Stanford University PhD students, set out to revolutionize web search. Their initial search engine, BackRub, used backlink analysis to determine relevant results—a stark contrast to existing search tools back then. The leap from BackRub to Google signaled a new era in information discovery, making “Google it” a global catchphrase on Google’s 27th Birthday.

The Spelling Mistake That Changed Everything

The story behind Google’s 27th Birthday traces back to a quirky mistake in 1997. Wanting a name that reflected their vision to organize immense information, Page and Brin landed on the mathematical term “Googol”—which means 1 followed by 100 zeros (10^100). The term, coined by Milton Sirotta (the nephew of mathematician Edward Kasner), perfectly symbolized the vastness Google aspired to handle.

During a crucial brainstorming session, Sean Anderson, a collaborator, searched for the “googol.com” domain. By accident, he typed “google.com” instead. Fortune favored the typo—the domain was available, and the slick-sounding name stuck. This happy error gave birth to the brand we celebrate today on Google’s 27th Birthday.

Why Do We Celebrate on September 27?

Although Google was officially incorporated on September 4, 1998, Google’s 27th Birthday is celebrated on September 27. The choice marks a significant internal milestone: it was the day when Google set a record for indexed web pages, establishing its reputation as the internet’s most capable search engine. Over time, this tradition has turned Google’s 27th Birthday into a nostalgic annual event, typically commemorated with a special Google Doodle and birthday offers.

The Journey from Start-Up to Search Giant

Google’s 27th Birthday is an ode to relentless growth and technological evolution. What began as a university project quickly transformed into a global powerhouse. Today, Google processes billions of daily searches and is synonymous with Internet knowledge, innovation, and accessibility. Its original spelling error even shaped a verb—“to Google”—that defines the very act of web searching.
