DOJ need to be careful to really only focus on mainly Search Engine Advertising and secondly (Programmatic) Display Advertising, excluding Social Media. I'd even split up display and SEA, due to them being somewhat different issues:
In Search, Google being a quasi-monopoly and on the other hand having control over publishers etc in Display, where they don't own the ad-space.
