The US justice department is opening a broad antitrust review into whether dominant technology firms are unlawfully stifling competition.
“The Department’s review will consider the widespread concerns that consumers, businesses and entrepreneurs have expressed about search, social media, and some retail services online,” DOJ said in a statement.
“Without the discipline of meaningful market-based competition, digital platforms may act in ways that are not responsive to consumer demands,” added the assistant attorney general Makan Delrahim, of the antitrust division.
The review will investigate practices of online platforms including Facebook, Alphabet’s Google, Amazon and Apple.
Facebook, Alphabet, Amazon and Apple did not immediately respond to requests for comment.
