Durante quanto tempo a rádio será analógica?

«It remains true that over the air broadcasting will be the principle distribution path for most public radio programs today and for the foreseeable future. But even in over the air radio broadcasting, the last enclave of the old analogue world, change is rapidly occurring. As of today, more than 600 public radio stations are moving to digital operations. By the end of 2007, we anticipate 350 stations to be on the air with digital signals, and of those more than 100 will be multicasting, serving their communities and listeners with not one, but two or more streams of public radio programming.
