How did the right get their vice grip of the airwaves, all the while arguing that they were being silenced and censored by a liberal media? This week, we look at the early history of American radio to reveal that censorship of far-right and progressive voices alike was once common on radio. And reporter Katie Thornton explains how, in the post-war and Civil Rights period, the US government encouraged more diverse viewpoints on the airwaves — until it didn’t. Plus, the technological and legal changes that led to conservative talk radio hosts like Rush Limbaugh taking over the airwaves.
