Brooke Gladstone’s The Influencing Machine is so remarkable that it is hard to describe. The best I can do is: it’s a book about the history and current controversies of the media, all done as a Spiegelman-style comic-strip narrative. Brooke herself (or at least an avatar) leads you through it all, and her ‘voice’—well known after her years as host of NPR’s On the Media—comes through loud and clear, thanks to Josh Neufeld's witty drawings. I learned a lot, including a lot that I should have known already, and enjoyed every minute.
