How It Happened:
Through legal processes, including antitrust trials, public comments, and policy proposals, delays and appeals prolong outcomes. The trial, which lasted 15 days in September 2024, focused on Google's alleged monopolistic practices in ad tech.
Why It Happened:
Concerns over market dominance and anticompetitive practices, such as Google's alleged manipulation of ad auctions and suppression of competitors, have driven this regulatory action. As stated in DOJ filings (Office of Public Affairs: Justice Department Sues Google for Monopolizing Digital Advertising Technologies), the aim is to unfetter markets and restore competition.
Future Projections:
The outcome may lead to more breakups or behavioral remedies, with AI-driven changes potentially outpacing legal outcomes. Appeals could prolong proceedings, shaping future regulatory approaches to big tech.
On-Premises Revolution in Ad Tech
What Has Changed:
Contrary to trends in other sectors, ad tech companies increasingly opt for on-premises solutions, relying on their own servers and co-located hardware rather than public clouds like Amazon Web Services (AWS), Snowflake, Databricks, or Google Cloud Platform. This shift is driven by the need for greater control over data, security, and performance, particularly for handling large data sets and ensuring low latency, as highlighted in industry analyses (AdExchanger: Why ad tech leads the on-premises revolution).
When It Happened:
This trend has been observed recently, with notable mentions in early 2025, aligning with the need for real-time ad tech operations.
Where It Happened:
The shift is global, affecting ad tech companies worldwide, with no specific geographic limitation.
Who Did It and Who Was in Charge:
According to industry reports, they are driven by ad tech companies themselves, with sector leaders preferring in-house solutions over public cloud providers like AWS and GCP.
How It Happened:
It happened organically as companies recognized the benefits of owning infrastructure and deviating from cloud trends, possibly due to cost-effectiveness and security needs over time. This includes investments in co-located hardware for better performance.
Why It Happened:
Key drivers are the need for low latency, data security, and long-term cost-effectiveness. Ad tech operations require real-time processing, and on-premises solutions offer better control and customization, as noted by industry experts like Srini Srinivasan of Aerospike (Why Ad Tech Leads The On-Prem Revolution | AdExchanger).
