The medium has been surprisingly resilient:
Despite all the disruption and change in the music industry, the size of radio’s audience has remained stable. Since 2004, annual market research has found that radio’s weekly reach is roughly 90% of Americans every year. The 92% of Americans that radio reaches every week listen to an average of two and a half hours of radio per day. And radio’s biggest users are not luddites. Among Millennials, the top listeners are 46% more likely to own a smartphone or tablet than their peers.
