The Trump government-led scrutiny into Google's ad tech market dominance alleged exclusive distribution deals with wireless carriers and phone makers to thwart competition.
A group of state attorneys alleged Google of conspiring with Meta Platforms Inc (NASDAQ: META) Facebook to manipulate the online auctions. It also became a subject of the DOJ investigation.
The probe would mark the DOJ's second case against Google following the government's 2020 antitrust lawsuit alleging dominance of the online search market.
"Our advertising technologies help websites and apps fund their content and enable small businesses to reach customers around the world," reasoned Google.
"The enormous competition in online advertising has made online ads more relevant, reduced ad tech fees, and expanded options for publishers and advertisers."
Google controlled about 28.6% of the $211.2 billion in U.S. digital ad spending in 2021, according to eMarketer, while Facebook made up 23.8% and Amazon.com Inc (NASDAQ: AMZN) 11.6%.
Apple Inc (NASDAQ: AAPL) is also under investigation by the DOJ over the App Store competitiveness.
