I always thought of alternative radio/music happening due to college radio becoming popular. College radio was always much more eclectic and avoided main stream music. At least it seemed to follow that path where I grew up as the alternative radio stations popping up all seemed to lift their playlists from the local college station's most popular and pop-oriented music.
