I think "worldview media" is a more appropriate term for the phenomenon. What form it takes isn't as important as the fact that it supplies enough content / entertainment / methods of consumption that one can subscribe to it and have 100% of their bandwidth filled, to the exclusion of competing narratives. Talk radio was an imperfect expression of this, because radio isn't portable in the same way that app-based social media + mobile devices / Fox News are. But it's entirely possible to prevent someone from ever being exposed to a contrary narrative, simply by filling all their available time.
