Brian Stelter is the host of CNN’s Reliable Sources, as well as the network’s chief media correspondent. But before he was the host of Reliable Sources, he was just a kid with a blog — a blog that obsessed over the coverage decisions, business models, and consequences of cable news.So he was the perfect person to have this conversation with. I’ve done — and continue to do — a lot of cable news. So I think a lot about the effect cable news has on the political system. How does it change the stories it covers? How does it decide what is and isn’t news? What are its biases? Who actually watches it? How has it been changed by Trump and Twitter? And, with apologies to Jon Stewart, is cable news hurting or helping America?Brian and I see the answers to some of these questions differently. But he’s one of the most thoughtful media analysts going today. Love it or hate it, cable news matters. So it’s worth trying to understand how it works, and why it works the way it does.Book recommendations:American Moonshot: John F.
