Actually, I find the KTWV story to be rather amazing. They were one of the first "New Age" stations in America, completely breaking away from the heritage station that preceded it and taking a real gamble on the format, while providing something completely different any of the formats they were speculated to flip to at the time. Then, when the new age format began to stall, they transitioned to the similar, "Smooth Jazz" format which was very successful, and then when that ship had finally sailed they again transitioned from "Smooth Jazz" to sort of KUTE style R&B, first only including classics and then slowly more modern stuff. They did all of this over many years without significantly changing air staff, logo, and call letters, as if no change had ever really been made. A truly evolved, but not really changed station.
