Sundar Pichai, CEO of Alphabet and Google, will testify in an antitrust fight over Google’s dominance in search and search advertising. Pichai will likely be questioned about Google’s investments to maintain competitiveness in search, particularly with the rise of smartphones, and innovation in search advertising. The government may inquire about Google’s payments to ensure its search is the default on smartphones. Google argues that these agreements are legal and that users have the option to switch to other search providers.
