To start with...

To paraphrase the late-great Tom "Big Daddy" Donahue,  Radio, as we know it today and have known it for the last twenty five years, is dead, and its rotting corpse is stinking up the airways. 
I say this with no joy, as I have been loosely, yet lovingly a part of the radio "biz" for forty years. The way we got here is well documented and I won't dredge it back up, but suffice to say, most of today's broadcast radio stations have been reduced to computer generated, cloned, satellite-fed, cost-cutted money pits.
Don't misunderstand, I am not one of those "anti corporate radio" types. While the executives at the big groups such iHeartMedia, Beasley, Cumulus, etc. certainly share responsibility for the current state of affairs, there a many other variables.
We have more choices than ever for their info and entertainment. Music formats have become ridiculously fragmented. Just within "Rock" itself, we have melodic Rock, Hard Rock, Grunge, Progressive, Glam, Punk, Metal and more. Some people will simply not listen to anything outside of their niche, their comfort zone.  
Couple narrowly focused listeners who have thousands of ways to hear whatever they want to hear  (usually at no cost) and you can see what a formidable obstacle traditional broadcast radio must overcome.
FM/AM broadcasters bear huge costs to just to operate at a minimal level. The equipment is expensive to buy and maintain, there's insurance, staffing, licensing, government agencies to satisfy, the list goes on. They are competing against dozens of other stations in their markets, all trying to reach the same population and all trying the carve a slice of the local advertising revenue.  All the while listeners are turning away in droves, sucked in by YouTube, Spotify & Sirius/XM. 
Radio has been down many times before and always bounced back. It survived the onslaught of television in the early 1950's. It survived  the death of AM Top 40. Can it do it again? Does anyone care enough to take a chance?
