Google acquired and maintained monopoly power in digital advertising, US judge rules

Alphabet’s Google illegally dominated two markets for online advertising technology, a federal judge said on Thursday, dealing another blow to the tech titan in an antitrust case brought by the U.S.

U.S. District Judge Leonie Brinkema in Alexandria, Virginia, ruled that Google unlawfully monopolized markets for publisher ad servers and the market for ad exchanges which sit between buyers and sellers. Antitrust enforcers failed to show the company had a monopoly in advertiser ad networks, she wrote.
