Google’s 28th Birthday Brings an AI Mode Quiz

Google's 28th birthday, marked with Google Doodles, brings a great deal of nostalgia and one of Google's latest search adventures. As the clock struck 28 on Sept. 27, 2026, Google put a vintage iteration of its early logo on its homepage. When clicked, users launched Google AI Mode to take a trivia quiz on Google history, Google company lore, and birthday fun. The birthday Doodle offers a glimpse of Google's past but also exposes how Google taps artificial intelligence today in Search. Instead of showing a commemorative image, the Doodle links the anniversary to an interactive AI-driven search experience.

Google Celebrates Its 28th Birthday

Google officially celebrates its birthday on September 27, although its corporate incorporation date is September 4, 1998. Larry Page and Sergey Brin formally incorporated Google Inc. on September 4, 1998, after developing the search engine project that eventually grew into one of the world's largest technology companies.

Google began using September 27 as its consistent birthday celebration date in 2006. The date connects to a major milestone related to the company's web indexing work. Google also created its first birthday-themed Doodle on September 27, 2002. Over the years, Google's birthday Doodles have become a way for the company to celebrate its history through different designs and interactive experiences. The 2026 Doodle continues this tradition with a visual reference to Google's early identity.

The Doodle Uses an Early Google Logo

 
The 2026 Google Doodle features a nostalgic logo inspired by Google's early days. Google describes the artwork as a celebration of its 28th birthday and uses the Doodle to highlight different moments from its history.

The official Doodle page also shares several facts about Google's Doodle tradition. The first Doodle appears in 1998 as an informal out-of-office message while Google's founders are away. The first animated Doodle arrives in 2000, while the company creates hundreds of Doodles around the world every year. This year's design therefore works as both a birthday greeting and a reminder of how the Doodle tradition develops alongside Google itself.

Clicking the Doodle Opens an AI Mode Quiz

The most notable part of this year's celebration comes after users click the Doodle. According to Search Engine Roundtable, the Doodle takes users into Google AI Mode, where they can participate in a trivia quiz focused on Google's history, unusual company moments, and birthday traditions. The quiz gives the birthday celebration an interactive element. Instead of only reading about Google's past, users can answer questions and test their knowledge. The experience also places AI Mode directly into a Google anniversary activity, showing how AI becomes part of the company's current Search experience. Google's official Doodle page similarly describes the birthday trivia quiz as a way to learn about Google's history, culture, and famous moments.

A Birthday Celebration With an AI Focus

The connection between the Doodle and AI Mode reflects the changes taking place in Google Search. Google continues to expand AI-based features and AI Overview optimization strategies that help users interact with information in more conversational ways. For Google’s 28th birthday, the company combines two different sides of its identity. The vintage logo represents Google's early search history, while AI Mode represents its current direction in Search. The quiz sits between these two ideas by using a newer search experience to explore older parts of Google's story.

The approach also gives users a simple way to interact with AI Mode without starting with a complicated research question. The quiz provides a familiar format while introducing Google's AI search experience through questions about the company itself.

Google Connects Its Past With Its Present

Google's 28th birthday Doodle shows how the company uses its anniversary to look back while highlighting its current technology. The vintage design recalls the early Google brand, while the AI Mode quiz brings the celebration into Google's newer search experience, alongside ongoing Google Search updates. The celebration also adds another chapter to Google's long-running Doodle tradition. From a simple out-of-office message in 1998 to interactive experiences today, Google Doodles continue to mark important moments and invite users to engage with the company's history.

For users who click on the birthday Doodle, the celebration becomes more than a homepage image. It becomes a short interactive journey through Google's past, delivered through one of the company's newer AI-focused Search experiences.
