The proposed breakup floated in a 23-page document filed late Wednesday by the U.S. 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.
Such changes would essentially result in Google being highly regulated for 10 years, subjecting it to oversight by the same Washington federal court that ruled the company maintained an illegal monopoly in online search and related advertising.
This time, the goal is to target websites hosting content intended to take advantage of site ranking, especially after earlier this year it launched a method to combat site reputation abuse.
The US Justice Department and a group of states have asked a federal court to force Google to sell Chrome, its popular web browser, a move that could fundamentally alter the $US2 trillion ($3 trillion) company’s business and reshape competition on the internet.
