They do have a winning recipe thats why they are still on the air. When KKBT flipped and KDAY's poor signal KPWR offically won the hip hop(despite being rythnmic) crown in Los Angeles. The only real threat they had was KXOL during 2006 but has since then died wayyyyyyy down. The only success KXOL did was drive away KKBT latino listeners. Its all about sales and demo and what they are doing now is way better compared years ago. The PD gotta appeal to what their core listeners wanna hear and in the Los Angeles radio market nothing last forever.
