Google faced a fresh federal court test on September 22, 2025, as US government lawyers asked a judge to order the breakup of the search engine giant's ad technology business. The lawsuit is Google's second such test this year after the California-based tech juggernaut saw a similar government demand to split up its empire rejected by a judge earlier this month.
