All those guys I mentioned above got radio play because their songs weren't dirty (except for Blas Duran). Radio stations like Radio Guarachita and a few others were almost exclusively dedicated to Bachata and Perico Ripiao.
I think what you're referring to the wave of bachateros who went mainstream and started to get played in radio stations that previously would have never played bachata. All of that is due mainly to one guy (Juan Luis Guerra and his Bachata Rosa album). That's the album that made it "cool" for Bachata to get played in the so called "mainstream" radio. That's when people from "La Capital" started to listen to Bachata and that was followed by a slew of young singers.
