Google CEO to Testify in Antitrust Case, Facing Questions on Search Dominance and Smartphone Deals

Google CEO Sundar Pichai will testify in the U.S. antitrust case against Google on Monday.

Pichai will likely be asked about Google's investments to keep search competitive as smartphones became prevalent.

The government may ask why Google pays billions to be the default search on smartphones.

The government argues Google illegally paid $10 billion annually to be the default search on devices to stay dominant.

Google argues the deals are legal and it invested to keep search and ads competitive. People can switch defaults if unsatisfied.
