The AI browser wars are just beginning - but I've already glimpsed how they will change the internet: David Richards

Why does the browser matter so much? Because it functions as the internet’s tollbooth.

Control it and you control attention, defaults, cookies, queries, and money. The browser market alone is worth approximately £250 billion. For search engines, the browser serves as a front door, shelf, and checkout counter in one. Win the browser and you win the market that funds the modern web.

That is why the browser wars matter. Get your popcorn ready.

Act I began in the mid-1990s with Netscape versus Microsoft. Netscape built the on-ramp to the web. Microsoft bundled Internet Explorer with Windows, cutting Netscape off at the knees. The move triggered a landmark antitrust case. The lesson was unambiguous: bundle the browser and you can win the market, but push too far and regulators arrive.

Act II arrived a decade later. Internet Explorer dominated until Firefox reignited competition.

Then in 2008, Google launched Chrome. It loaded pages faster, crashed less, and integrated every Google service users relied on. Within four years, Chrome overtook both rivals. Today, it commands roughly 70 per cent of global usage. Chrome became Google’s distribution engine for advertisements, analytics, and Android.

Act III began last week when OpenAI launched ChatGPT Atlas, a full web browser with ChatGPT at its core. This is not a plugin. It represents a new front door to the web with an always-present sidebar, page summarisation, and an agent mode that completes tasks for you.

If Atlas gains share, it threatens Chrome’s moat and, by extension, Google Search, because it changes what happens after you type your intent. The query becomes a conversation. Tabs become tasks.

This shift matters profoundly. People do not want ten blue links anymore. They want answers. Large language models deliver a fundamentally different experience.

I experienced this directly last week when I needed a generator battery. Google gave me a wall of advertisements, affiliate links, and generic lists. After several clicks, I ordered one that did not fit. ChatGPT asked for the make, model, temperature range, and usage requirements. Within seconds, it provided exact specifications, compatible batteries, and maintenance advice. One approach sold me noise. The other gave me knowledge.

The implications extend far beyond consumer frustration. Entire industries have been built on search engine optimisation, paid placement, and link ranking. AI sweeps that away.

Instead of competing to appear on Google’s first page, companies will fight to become the single recommended answer. That shift will rewrite digital marketing, product discovery, and online commerce almost overnight.

History shows distribution beats purity. Microsoft won Act I by bundling Internet Explorer. Google won Act II by making Chrome the fastest path to its ecosystem. OpenAI understands this pattern. To change behaviour at scale, you ship your own browser and control the experience end to end. Atlas bets that value has moved from query to conversation, from page views to outcomes.

What happens next? Expect counter-moves. Google will push Gemini across Chrome and Android. Apple will build more intelligence into Safari. Microsoft will not sit out another browser war. Regulators will watch defaults and data flows closely.

After Act I, Microsoft kept Windows but lost the web to Google. After Act II, Google built an empire on the browser it controlled. Act III brings us back to Page’s vision. He said AI would become the ultimate search engine. The irony is that the very thing he foresaw may well arrive inside a browser that is not Google’s.
