This season we've traced the creation of Big Oil's big propaganda machine. In this episode, the season finale, we look at what can be done about it now that it has delivered us into an era of disinformation. NYU journalism professor Jay Rosen and former FCC commissioner Nicholas Johnson join us to talk about everything from the Fairness Doctrine to cable access to today's "post-fact" world, and where we can really go from here. Special thanks to Mary Catherine O'Connor for additional reporting.
