How did Google's illegal ad monopoly work?

a year ago

Google was found to operate an illegal monopoly in the ad tech space, specifically in publisher ad servers, buy-side ad exchanges, and advertiser-side ad networks.
The ruling highlights Google's anticompetitive practices, such as giving preferential treatment to its own ad exchange over competitors.
Google introduced features like 'First Look,' 'Open Bidding,' 'Last Look,' and 'Project Poirot' to limit competition and maintain dominance.
'Unified Pricing Rules' were implemented to counteract publisher strategies to reduce reliance on Google, but still favored Google's exchange.
Publishers attempted to break free from Google's monopoly using 'header bidding,' but Google co-opted this practice with 'Open Bidding,' charging competitors a fee.
The court rejected Google's argument that the ad tech market is a two-sided marketplace, treating each component as a separate market.
Google's dominance in the publisher ad server and ad exchange markets was deemed a monopoly, with illegal and anticompetitive behavior.
The ruling underscores how Google's ad revenue fueled its ecosystem, allowing unchecked growth and reducing accountability in other business areas.
Microsoft's competitive strategy against Google included offering equivalent features for free to enterprise clients, highlighting the challenges of competing with Google's ecosystem.
