I've been presenting a folk program on community radio since 1976 and I've definitely notice a reduction in physical CD traffic coming my way in the past few years. I'm in Australia, so international postal costs might be a factor for non-Australian labels, but the trend is definitely towards encouraging presenters to download music.

Most of the presenters in my situation are volunteers and may not have the time or inclination to sit in front of a computer chasing downloads. One common complaint is that presenters like to have comprehensive album sleevenotes while we're on air and those useful, objective, sleevenotes have largely been replaced by promotional blurbs on web pages.

There have been many long and heated discussions among radio people about the merits of this method of distribution.
