'Liberal' talkradio set to challenge right-wing ranting on US AM radio: "From the advent of Limbaugh in the late 1980s to today, however, nearly all of that talk radio programming has been of the right-wing variety. Limbaugh's success spawned an entire industry of Rush-wannabees and Rush clones, even shifting long-time non-political talk hosts into making right-wing proclamations in order to retain market share. The industry discovered right-wing talk radio, found it profitable, and thought that conservative talk was the only kind of talk that could work on the AM dial."
