An AI Replay of the Browser Wars, Bankrolled by Google

A quarter of a century ago, when Microsoft Corp. used its dominance of the personal computer market to force people to use Internet Explorer, it famously led to a devastating antitrust lawsuit loss that some believe held the company back for more than a decade. Only now, revitalized by Chief Executive Officer Satya Nadella’s quick moves in artificial intelligence, is the Windows-maker back on top. As AI rivalries intensify, Google is now trying to put Microsoft through its ’90s nightmare again.

The search giant is funding the Browser Choice Alliance, an industry group involving Google and a number of smaller browser makers, such as Opera, Vivaldi and others, set up to put pressure on Microsoft. The complaint, as it was back then, is that Microsoft is once again using its ownership of the Windows operating system to give its own browser an unfair leg up — at a moment that some feel is as pivotal as the emergence of the internet.

The Alphabet Inc. unit is not the only financial backer of the BCA, I’m told by two people familiar with its structure, but it is comfortably the largest. This isn’t surprising because it has the most to lose: Longtime rival Microsoft, with its partner OpenAI, sees a window to take on Google’s search dominance, and were Microsoft’s to become the most popular AI browser, it would steal considerable market share.

Google would not confirm the size of the company’s contribution to the BCA. “We’ve been open about our concerns with Microsoft’s well–documented use of dark patterns that make it harder for Windows users to keep using their preferred browser,” a spokesman said.

The new “Browser War” is brewing thanks to the desktop or laptop computer’s position as one of the biggest early battlegrounds in AI. While the smartphone has become people’s most frequently used computing platform, the desktop (or laptop) has retained its place for accomplishing real work — the kind of tasks AI makers say they can help with the most. As such, we’re seeing a slew of new or improved browsers hit the market, with new entrants such as the Browser Company’s Dia browser or Perplexity’s Comet. OpenAI is said to be working on its own. Winning the browser is seen as critically important as it can help forge new habits. Perplexity, for instance, told me that users who installed Comet were making three times more AI queries every day than they had been previously.

Following suit, Microsoft recently announced that Edge — the default browser for Windows users — had received a significant AI upgrade. The company’s CoPilot assistant is now embedded in the browser and can take control of a user’s tabs to carry out tasks such as making a booking, much like a human might (at least in theory).
