Title:
Adult_contemporary_music

Context:
The soft AC format may soon be facing the demographic pressures that the jazz and big band formats faced in the 1960s and 1970s and that the oldies format is starting to face today, with the result that one may hear soft AC less on over-the-air radio and more on satellite radio systems in coming years. Much of the music and artists that were traditionally played on soft AC stations have been relegated to the adult standards format, which is itself disappearing because of aging demographics.
