 Just as radio in the 80s had the "urban versus churban" competition, R & B oldies radio was dividing into two camps—the straight urban oldies stations targeting African Americans, and the "Jammin' Oldies" stations with a wider audience that included both blacks and whites.On Jammin' Oldies radio, DJ's were often mostly white or a variety of racial groups.Many of the songs played had crossed over to top 40 radio, while R&B stations continued to play more hits, including ballads, not familiar to top 40 fans, especially if those songs were not singles.
