The antitrust trial between the US Justice Department and Google concludes this week after a five-month legal battle, with the judge expected to rule in three to four months. The US Justice Department accuses Google of using its market dominance to stifle competition, particularly through default search engine contracts worth billions. While Google's defense argues its success is due to superior technology, the allegations suggest these contracts hinder market entry for potential competitors. Judge Amit Mehta’s ruling could significantly impact Google’s operations and potentially reshape the competitive landscape of the internet search market.
