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 (DOJ) is preparing aggressive remedies in the wake of its antitrust victory against Google, including a potential forced sale of the Chrome browser, Bloomberg reports.
