Federal Judge to Decide Fate of Google's Ad Manager

The U.S. Department of Justice (DOJ) seeks a remedy for Google's advertising technology monopolies, focusing on the Ad Manager platform.

Trial Conclusions and Arguments

After closing arguments on 2023-11-21, Judge Leonie Brinkema must rule on the DOJ's proposal to dismantle Google's advertising marketplaces, including AdX. Google's defense emphasizes that breaking up Ad Manager could be technically unworkable.

Potential Impacts and Next Steps

A forced sale or structural changes could impact web competition significantly. However, the decision's implementation might be delayed due to potential appeals, which Judge Brinkema acknowledged could complicate enforcement.

• The DOJ seeks the breakup of Google's ad monopolies to restore competition.
• Google argues a breakup of Ad Manager would be technically challenging and risky.
• The decision could face delays from appeals, affecting enforcement.
