Brooke Gladstone and Josh Neufeld made The Influencing Machine: Brooke Gladstone on the Media which is a comic about how the media works. It talks about bias and how objectivity doesn’t really work, but also about the history of democracy and media consolidation. The book is drawn really well, clear and effective in conveying its information. Comics like this are so good at doing introductions to complicated topics.
I started the book really enthused about it, but as it went on I realized it was never going to get beyond the introductory stuff. It was still good, but since the media is something I read about a lot in non-book form I was a little underwhelmed by the content. But as an introduction, it was pretty good.
