Have them, yes, but when was the last time you sat down just to listen to the radio? The only radios I have are for emergencies, not entertainment. Even in the car, I use my phone to play my iTunes library.
No one has sat down to listen to the radio since the 1950's. Radio is still a widespread and popular media, enjoyed by millions of people around the world. It has found a niche, just like television probably will.
