Top Justice Department antitrust officials have decided to ask a judge to force Alphabet Inc.’s Google to sell off its Chrome browser in what would be a historic crackdown on one of the world’s biggest tech companies.

Now, Alphabet, Google’s parent company, may be forced to sell Chrome. The browser, which was launched in 2008 and integrates with Google’s search engine, is used today by some 3.4 billion people worldwide.

The U.S. Department of Justice is preparing to ask a judge to consider pushing Alphabet’s Google to divest its Chrome browser, according to reports Tuesday, as the Biden administration’s top antitrust officials makes a last push to crack down on the tech industry before leaving office.
