Mine would be the fresh new sound of 105, Hot 105/107 lol that came to an end when they were pressured into canning most of the rap. A close 2nd is the period of time when 107.5 first came on the air because it caused 106.3 to turn to a hip hop heavy mainstream urban format. That, of course, didn't last long because Radio One bought both stations and Power reverted to regularly playing rap only at night. Last would be Kiss fm, WNCI was threatened enough by them to completely rip off their presentation.
