The US Department of Justice (DOJ) is once again pushing for Google to sell its Chrome browser and divest its control in online search.In a new filing, the DOJ reaffirmed its demand that Google must sell Chrome and stop paying companies to make Google Search the default option.The DOJ argues that selling Chrome would level the playing field for competitors and give rival search engines a fair shot at reaching users.The final decision on how Google must change will be made in April when the judge reviews proposals from both the government and Google.
