Google Turns 28: How Search Evolved Into the AI Era

By Yash KharePublished Sep 27, 202610 min read

If you opened Google today, September 27, 2026, you probably saw an old friend: the company's very first logo from 1998, brought back as a birthday Doodle. Google is celebrating its 28th birthday — and it chose a revealing way to do it. The Doodle nods to the '90s, then points visitors toward Google's newest AI features.

That pairing sums up the story better than any timeline. The product that taught the world to "google it" is now rebuilding Search around AI that writes answers instead of just listing links. Here is how Google got from a Stanford research project to AI Mode and Gemini — and what that shift means for everyone who still types questions into a box.

Google's 28th birthday: what happened today

Google's homepage Doodle for September 27, 2026 is titled "Google's Birthday 2026." Rather than new artwork, it revives the company's first-ever logo, created in 1998. In its Doodle description, Google invites people to let the vintage logo take them back to the '90s and then to check out its newest AI innovation. Reports also describe an interactive element that lets visitors browse past Doodles that ran on their own birthdays.

Doodles themselves started small. Google says the first one, in 1998, was essentially an out-of-office note: a stick figure added to the logo when the founders went to the Burning Man festival. Nearly three decades later, the birthday Doodle is used to frame Google's own history — and, this year, its AI pitch.

September 27 vs September 4: why two dates?

This is the part that confuses most people searching "when is Google's birthday." Google has two important dates, and they mean different things:

September 4, 1998 is the legal one. That is when Google Inc. was incorporated, shortly after Sun Microsystems co-founder Andy Bechtolsheim wrote a $100,000 cheque to the company in August 1998.
September 27 is the celebration. Google has marked its birthday on this date since the mid-2000s, and it is when the birthday Doodle appears.

Why September 27? Google has never given a definitive reason. In the early years the celebration drifted around September, and Google once joked that the date moved depending on when people felt like having cake. A widely repeated explanation ties September 27 to a record-setting milestone in the size of Google's search index during the mid-2000s, but that link is not officially confirmed — treat it as a popular theory, not a fact.

Either way, the arithmetic is simple: from 1998 to 2026, Google is 28 years old.

Where Google started: BackRub at Stanford

Before it was Google, it was BackRub — a research project Larry Page and Sergey Brin built as PhD students at Stanford University in the mid-1990s. Its big idea was to rank web pages partly by the links pointing to them, treating each link as a kind of vote. That approach, later known as PageRank, gave far more useful results than engines that mostly counted keywords.

The project was renamed Google, a play on "googol," the number 1 followed by 100 zeros — a hint at how much information the founders wanted to organise. After incorporation, the young company worked out of a rented garage in Menlo Park, California, before eventually settling in Mountain View.

How Google changed Search, one layer at a time

For its first decade, Google Search was famous for being plain: one box, one button, ten blue links. What changed over the next 28 years was not the box but what came back from it. Each step pushed Search from "find pages that match these words" toward "understand what this person is actually asking."

Sep 4, 1998 Google Inc. is incorporated; Search runs on PageRank-style link analysis.
Jul 2001 Google Images launches, making Search about more than text pages.
May 16, 2007 Universal Search blends images, news, video and maps into one results page.
Nov 2008 Voice search arrives in Google's mobile app for iPhone.
May 16, 2012 The Knowledge Graph starts showing facts about people, places and things — Google's "things, not strings" shift.
Oct 2, 2015 Alphabet becomes Google's parent company.
May 17, 2017 Google Lens is announced, letting the camera become a search box.
Oct 25, 2019 Google starts using the BERT language model to understand queries in Search.
Dec 6, 2023 Google introduces its Gemini family of AI models.
May 14, 2024 AI Overviews begin rolling out to everyone in the US.
May 20, 2025 AI Mode, a fully conversational search experience, rolls out to all US users.
May 19, 2026 Google says AI Mode has passed one billion monthly users.

From search results to answers

Look at that timeline and a pattern appears. Google kept adding new ways to ask and new kinds of answers:

Richer results: images, news, video and maps started appearing alongside links, so you often didn't need to click anywhere.
Knowledge, not just pages: the Knowledge Graph let Google recognise that "Taj Mahal" is a monument with a height, a location and opening hours — not just a string of letters.
New inputs: voice search let you speak a question, and Lens let you point a camera at a plant, a menu or a maths problem. Searching became multimodal long before chatbots arrived.
Language understanding: models like BERT helped Search read the small words in a query — "to," "for," "without" — that change what a person actually means.

Each of these moved Google from pointing you to information toward handing you the information directly. Generative AI is the biggest leap in that same direction.

Google's AI era: where Gemini fits

Gemini is two things at once, which is why it can be confusing. It is Google's family of AI models, first introduced in December 2023, and it is also the name of Google's AI assistant app (which replaced the earlier Bard brand in 2024). In Search, Gemini models do the heavy lifting behind AI Overviews and AI Mode.

At Google I/O on May 19, 2026, Google's head of Search, Elizabeth Reid, said Gemini 3.5 Flash had become the default model in AI Mode globally. Google ships new Gemini versions quickly — in September 2026 alone the company released Gemini 3.8 Flash and a Gemini 3.8 Live model with a video avatar for businesses — so the exact model behind a given Search feature can change without much fanfare.

Gemini is also spreading beyond Search. Google is phasing out Google Assistant in favour of Gemini on Android devices, and Gemini is built into Gmail, Docs and other Google products. Search is the most visible piece of a much bigger AI strategy.

What is different about Search now?

Here is the simplest way to understand the change. Classic Google Search was a librarian who pointed you to the right shelves. AI-powered Search is more like a research assistant who reads several of those books and gives you a summary — with the sources listed underneath.

AI Overviews

AI Overviews are the AI-written summaries that appear at the top of many regular Google results, with links to the pages they draw from. Since Google I/O 2026 you can ask a follow-up question straight from an AI Overview and continue the conversation.

AI Mode

AI Mode is a separate, fully conversational search experience. You can ask long, complicated questions, ask follow-ups, and upload images or files. According to Google, AI Mode passed one billion monthly users just a year after launch, with queries more than doubling every quarter. It is also available in more languages — we covered its launch in Hindi earlier this month.

A new kind of search box

At I/O 2026 Google also redesigned the search box itself, calling it the biggest upgrade to it in over 25 years. The new box offers AI-powered suggestions and accepts text, images, files, videos and even open Chrome tabs as input, in countries where AI Mode is available.

Why this matters to you

Everyday users get faster answers to complex questions, but should still check the linked sources. AI summaries can be wrong, and a confident paragraph is not the same as a verified fact.
Students and researchers can use AI Mode to get oriented on a topic quickly, then go to original sources for anything they plan to cite.
Creators and publishers face a real shift: when Google answers a question on the results page, fewer people may click through to websites. How much traffic changes varies widely by topic and site.
Businesses increasingly meet customers inside AI answers, not just on a list of links — which makes accurate, clearly written information about products and services more important than ever.

What comes next for Google Search?

It helps to separate what Google has actually shipped from what it has only announced:

Available now

AI Overviews and AI Mode, powered by Gemini models, in many countries and languages.
Follow-up questions from AI Overviews into a conversation (live on desktop and mobile since May 2026, according to Google).
The redesigned, multimodal search box, where AI Mode is available.

Announced, rolling out gradually

Information agents that monitor the web around the clock for things you ask them to track, such as a new apartment listing. Google said these would launch in summer 2026 for Google AI Pro and Ultra subscribers.
Agentic booking for local services, including Google calling businesses on your behalf in select categories, announced for a US rollout in summer 2026.
Generative UI tools that build custom dashboards and mini-apps inside Search, starting with paid subscribers in the US.

Availability of these features varies by country, language and subscription, so check what you actually see in your own Google app. If you are new to the idea of software that acts for you, our guide to personal AI agents explains what they can do and where to be careful.

What Google has not announced is an end to traditional web results. Links, source citations and the classic results page still exist alongside the AI features. Where the balance settles is the open question of Google's next decade.

Key takeaway

Google turns 28 still best known for one search box — but what that box does has changed from listing links to writing answers with Gemini.
