If you haven't noticed; smartphones and Internet tech has become the hand held, voice recognition, go-to competitor to radio and TV. The vast majority of people still listen to their vehicle radio while driving, but have what amounts to a super computer in their pocket or purse that they rely on for education, communication, shopping, entertainment, news, and 24/7 accessing their social circles. There's no un-ringing that bell. Making believe one can just go back to the days before smartphone and Internet tech wasn't around to somehow recapture the days of our youth, amounts to tilting at windmills.
Radio isn't dying, but it's had no choice but to evolve within the level of competition that wasn't around when radio was the only thing.
