Google is currently facing an antitrust trial led by the U.S. Department of Justice, stemming from changes it made in 2019 that limited publishers' ability to divert ad sales to competitors. Internal documents reveal that Google anticipated backlash from publishers, who were using a feature to reduce their reliance on Google's ad services and often preferred to sell through rival exchanges. As a result, Google employees discussed strategies to present the changes alongside more favorable updates to mitigate potential pushback. The DOJ's evidence includes emails showing that Google was aware publishers were willing to accept lower returns in exchange for working with lower-fee competitors. The trial could result in significant consequences for Google, including the potential requirement to divest parts of its ad business. This case highlights ongoing concerns about monopolistic practices in the online advertising market.
