The US Media Landscape
How the most commercially driven media system in any major democracy evolved, fragmented, and polarized.
From Three Networks to Infinite Fragments
For most of the postwar era, Americans received their news from a remarkably small number of sources: three broadcast networks (ABC, CBS, NBC), a few national newspapers, and local outlets. This created a shared information commons - most Americans saw roughly the same news. The FCC's Fairness Doctrine (1949-1987) required broadcasters to present contrasting views on controversial issues, reinforcing centrism.
The media environment fragmented through several waves. Cable news (CNN 1980, Fox News 1996, MSNBC 1996) created 24-hour news cycles that rewarded opinion and conflict. The repeal of the Fairness Doctrine in 1987 allowed openly partisan broadcasting. Talk radio (Rush Limbaugh launched in 1988) created a parallel conservative information ecosystem. The internet and social media completed the fragmentation, giving every viewpoint its own platform and algorithm-optimized echo chamber.
