Radio will still remain the norm for remote and rural areas where technology (DSL/4G internet) have yet to make a footprint: where pertinent information is still reliant on radio. Think moreso farmers, who are out in the fields with no internet connection all day. Weather, and even farm reports matter to them, along with the local news. Or even mountainous areas, where people live "off the grid": radio is their only window to the outside world.
One of the millions of reasons why radio sucks now is that back a generation or so, radio looked "up" to their listeners -- treating them like a VIP customer at a restaurant because the listeners could easily go elsewhere. They seemed to speak directly to them as if they were their only listener, they did contests and promotions that were designed to make the listener stay tuned in all day long, they took their calls and responded to requests. The dj's would do public appearances where listeners would line up to speak/meet/get autographs from them.
Now all you have are stations and jocks (those who remain) who look down on their listeners, reading generic liners with a "phoning-it-in/who really gives a rat's ass" attitude. If you don't like their station and punch in another one, chances are you're still listening to another station from that same company who owns half the stations in town. Contests are uncreative or non-existent. Nobody (outside of talk radio) takes their calls after the morning show since it's all voicetracked, automated or syndicated after 10AM. If the DJ's that are left do an appearance, people walk past them as if they are selling and demo-ing AS SEEN ON TV products.
And, although the "payola" scandals of the 50s hit radio pretty hard, it is back in a different form where most of the music that sits in their 100-, 200-, or 300-song "playlists" is from record label bigwigs who "subsidize" some of the station owner's bills (royalties, concert promotions, commercials,...). Pretty much it is just "invisible" money that goes back and forth between the label and the stations on a daily basis.
But you know that radio is in dire straits when the top of the hour national network news reports' 1st commercial break at 12 Noon ET is for boner pills more times than not.
