by Jerry CayfordThe Google advertising technology trial is a very big deal. The ad tech trial is the third of three cases in which Google was accused of illegal monopolization, all of which Google lost. So, I’m settling for the most general of summaries, and leaving it at that: the Google ad tech trial lies at the intersection of most of the forces shaping our society’s present and future. So, those are the three parts: publisher ad servers, ad exchanges, and advertiser ad networks. DOJ’s structural remedies would deprive Google of the ability to re-monopolize ad tech, while behavioral remedies alone would not.
