Google celebrated its 28th birthday on September 27, 2026, with an animated Doodle on its homepage that pulled from the company’s early visual history. If you have ever noticed that Google’s birthday falls on September 27 but wondered why — given that it was not incorporated that day and did not register its domain that day — the answer is a piece of competitive history that most of the anniversary coverage gets wrong.

The Timeline Most Outlets Skip

  • September 15, 1997: Larry Page and Sergey Brin register the google.com domain.
  • September 4, 1998: Google is officially incorporated as a company in California.
  • September 7–8, 1998–2004: The company celebrates its birthday on various early-September dates in its first years.
  • 2006 onwards: September 27 became the consistent birthday date used by Google.

The reason for the shift to September 27 is attributed in internet history accounts to a competitive announcement: Yahoo! had claimed that its search index had surpassed Google’s page count, and Google responded with a public announcement that its own index had expanded to a record size. The September 27 announcement date became the birthday the company chose to mark going forward. It stuck, and has remained the official Google birthday date for the past 20 years.

The Cheque That Came Before the Company

Sun Microsystems co-founder Andy Bechtolsheim wrote a $100,000 cheque to “Google Inc.” in the summer of 1998 — before Google Inc. legally existed. Page and Brin could not cash it immediately because the legal entity the cheque was made out to had not yet been incorporated. They incorporated the company partly to be able to deposit the money.

The early servers were built partly from Lego bricks — the chassis chosen because it was cheap, modular, and allowed the hard drives to be slotted in and out easily in Susan Wojcicki’s Menlo Park garage, which served as the original headquarters. That origin is now part of the official mythology, but the Lego-server detail is often absent from anniversary retrospectives.

Where Google Is in 2026

Alphabet, Google’s parent company, crossed a $4 trillion market capitalisation milestone in January 2026, making it one of a small number of companies in history to reach that valuation. Its business has diversified substantially from its search origins — cloud computing, AI products, autonomous vehicles, and healthcare technology all operate under the Alphabet umbrella.

The same company that ran on garage servers assembled with toy bricks now operates data centers running on energy procurement agreements that Alphabet has announced, including nuclear and geothermal sources, to power AI workloads.

The Google homepage Doodle is live on September 27 each year. The 29th birthday will be on September 27, 2027.
