US regulators want a federal judge to break up Google to prevent the company from continuing to squash competition through its dominant search engine after a court found it had maintained an abusive monopoly over the past decade. The proposed breakup floated in a 23-page document filed late Wednesday by the Department of Justice calls for sweeping punishments that would include a sale of Google's industry-leading Chrome web browser and impose restrictions to prevent Android from favoring its own search engine, per the AP. A sale of Chrome "will permanently stop Google's control of this critical search access point and allow rival search engines the ability to access the browser that for many users is a gateway to the internet," DOJ lawyers argued in their filing.

Although regulators stopped short of demanding Google sell Android too, they asserted the judge should make it clear the company could still be required to divest its smartphone operating system if its oversight committee continues to see evidence of misconduct. The broad scope of the recommended penalties underscores how severely regulators operating under President Biden's administration believe Google should be punished following an August ruling by US District Judge Amit Mehta that branded the company as a monopolist. The DOJ decision-makers who will inherit the case after President-elect Trump takes office might not be as strident. The court hearings in Washington, DC, on Google's punishment are scheduled to begin in April and Mehta is aiming to issue his final decision before Labor Day.

If Mehta embraces the government's recommendations, Google would be forced to sell its 16-year-old Chrome browser within six months of the final ruling. But the company certainly would appeal any punishment, potentially prolonging a legal tussle that has dragged on for more than four years. Google has previously asserted the DOJ is pushing penalties that extend far beyond the issues addressed in its case. The DOJ also wants the judge to ban Google from forging multibillion-dollar deals to lock in its dominant search engine as the default option on Apple's iPhone and other devices. It would also ban Google from favoring its own services, such as YouTube or its recently-launched artificial intelligence platform, Gemini.

Regulators also want Google to license the search index data it collects from people's queries to its rivals, giving them a better chance at competing with the tech giant. On the commercial side of its search engine, Google would be required to provide more transparency into how it sets the prices that advertisers pay to be listed near the top of some targeted search results. Wary of Google's increasing use of artificial intelligence in its search results, regulators also advised Mehta to ensure websites will be able to shield their content from Google's AI training techniques. The measures, if they are ordered, threaten to upend a business expected to generate more than $300 billion in revenue this year. (More Google stories.)
