The tech giant, which wrapped up its arguments in the federal monopoly trial, simply says it has the best product.

An expert witness testifying for Google says an antitrust case brought against the tech giant drastically underestimates the company's competition.

The U.S. government’s monopoly case relies on the definition of digital ad markets, and whether Google unfairly controls them.

Google’s technologies offer advertisers and publishers a safe ecosystem of tools to transact amid the intensely competitive world of online advertising, the company argued in federal court this week to counter Justice Department allegations that it is an illegal monopoly.

Economist Mark Israel reported that when all online display advertising is accounted for, Google gets just 10% of the U.S. market share.
