From a New York Times story by Elizabeth A. Harris, Alexandra Alter, and Adam Bednar headlined “A Trial Put Publishing’s Inner Workings on Display. What Did We Learn?”:

Lawyers for the Department of Justice and for Penguin Random House delivered their closing argument on Friday in a case that will determine whether the publisher, the country’s largest, can buy one of its rivals, Simon & Schuster.

The case, which will be decided in the fall by Judge Florence Y. Pan, focused on the effects of consolidation on publishing, an industry that has already been dramatically reshaped by mergers in recent years.
