Google’s Secret Project Bernanke Used Past Bid Data To Boost Tech Company’s Win Rate In Advertising Auctions

Google for years operated a secret program that used data from past bids in the company’s digital advertising exchange to allegedly give its own ad-buying system an advantage over competitors, according to court documents filed in a Texas antitrust lawsuit.

The program, known as “Project Bernanke,” wasn’t disclosed to publishers who sold ads through Google’s ad-buying systems. It generated hundreds of millions of dollars in revenue for the company annually, the documents show. In its lawsuit, Texas alleges that the project gave Google, a unit of Alphabet Inc., an unfair competitive advantage over rivals.
