Radio has always been radio. Only real difference is that all the stations merged as soon as it became legal. After that basically all geographic music scenes died... And as a result to be a hit in an area you got to be a national hit... Since you got to pay for national spins instead of local spins now it's much more expensive to get on the radio...
Radio is much less important than it used to be, but it will always have some value do to its centralized nature.
