Chris Sagers, the James A. Thomas Professor of Law, appeared in various media recently on a variety of pending antitrust issues.

Sagers wrote his own piece in Slate on the Federal Trade Commission’s historic lawsuit against Facebook, and also spoke about the case with Agence-France Presse.

He spoke with both Publishers Weekly and Bloomberg about the pending acquisition of book publisher Simon & Schuster, by Penguin Random House or the News Corp subsidiary HarperCollins. The deal would leave only four major publishers of English-language trade books in the entire world, each of which would be a unit of the handful of multinational conglomerates that largely control mass media.
