A US District Court ruled in April that Google "wilfully engaged in a series of anticompetitive acts to acquire and maintain monopoly power" in ad exchange and ad server markets. Magnite, described as the largest independent sell-side platform in the advertising industry, filed a federal lawsuit against Google, accusing the company of unlawfully monopolizing ad exchange and publisher ad server markets. Google denied these allegations.
