In the 1970s, talk radio was hitting its stride, with hosts and listeners from all political persuasions. But the radio dial was about to change forever. Community needs assessments, requirements to offer public service programs and multiple perspectives, and limits on how many stations a single company could own were all eradicated. Technological and legal changes would consolidate the radio industry exponentially, allowing conservative talk radio hosts like Rush Limbaugh to take over the airwaves. In this episode, we look at radio’s last four decades to understand how we got to where we are today, and how conservative talk radio came to dominate a medium that once thrived on varied viewpoints.
