On November 10, 2011, Rikard Lindquist, a Finance Manager for Strategic Partnerships at Google, forwarded an internal email with a presentation regarding the display advertising ecosystem.
This document, which is currently part of a court case against Google (Case 1:23-cv-00108-LMB-JFA), reveals Google’s perspective on the evolution of display advertising at the time.
The lecture, dubbed Display Ecosystem Boot Camp, traces the history of display advertising from its inception to the rise of real-time bidding and ad exchanges. It provides a thorough view of the major actors and technology that have shaped the business over time.

According to the paper, display advertising began with direct sales between publishers and advertisers or agencies. This technique, known as reservation or direct buy, featured advertisers purchasing space directly from a publisher’s sales department under predetermined impression goals, budgets, and campaign dates.
As the industry expanded, publishers encountered difficulties with unsold inventory, known as “remnant” inventory. This resulted in the rise of ad networks, which aggregated publisher ad space and sold it to advertisers looking to reach a larger audience. The presentation mentions numerous big ad networks from the time, including Advertising.com and Glam Media.
However, the ad network model has some limitations. The document discusses issues such as lack of transparency, network proliferation, daisy-chaining (where networks resold inventory to other networks), and arbitrage (buying low and selling high without contributing value).

To overcome these issues, yield managers arose. Rubicon, Admeld, and PubMatic all provided services that helped publishers manage partnerships with different ad networks. Their goal was to maximize total yield by distributing available impressions across buyers.
The presentation then presents the concept of ad exchanges, which are auction-driven technological platforms that allow for the purchase and sale of ad inventory. Google’s DoubleClick Ad Exchange, Microsoft Advertising Exchange, and Yahoo’s Right Media are used as examples.
The document explains in detail how Google’s DoubleClick Ad Exchange (AdX) operated. It explains how vendors make merchandise available, buyers create targeted campaigns, and the auction mechanism matches inventory to the highest bidder in real time.

AdX offers two basic buying options: a user interface (UI) similar to AdWords and real-time bidding (RTB). RTB is defined as a feature that enables buyers to examine each impression in real time and propose bids using their own algorithms and data.
The presentation also discusses the integration of AdX with Google’s AdSense and AdWords products, demonstrating how these systems interact throughout the auction process.
As RTB gained popularity, different sorts of businesses arose in the ecosystem. The document covers trading desks (divisions of agency holding companies that manage exchange buying), demand-side platforms (DSPs) such as MediaMath and Turn, and audience data providers such as eXelate and BlueKai.
The presentation concludes with an explanation of some AdX features geared toward publishers, such as the ability to keep inventory anonymous to protect direct sales channels and “dynamic allocation,” a yield maximization feature in DoubleClick for Publishers (DFP) that compares AdX bids to other demand sources in real time.
