Google’s dominance of internet search faces major challenge in legal showdown with US regulators

The US government is taking aim at what has been an indomitable empire: Google’s ubiquitous search engine that has become the internet’s main gateway.

The legal attack will swing into full force Tuesday in a Washington DC federal courtroom that will serve as the battleground for the biggest US antitrust trial since regulators went after Microsoft and its dominance of personal computer software a quarter century ago.

The 10-week trial before US District Judge Amit Mehta is expected to include potentially revelatory testimony from top executives at Google and its corporate parent Alphabet, as well as other powerful technology companies.
