The success of Dees at their Memphis radio station, combined with his TV appearances and hit music, motivated station owner RKO General to offer Rick the morning radio show in Los Angeles at 93KHJ AM. Dees helped their ratings, but AM music radio was rapidly losing ground to FM. When KHJ switched to country music, Dees left KHJ, taking a morning position at KIIS-FM in July 1981. In a short time, he turned KIIS-FM into the #1 revenue-generating radio station in America, with an asset value approaching half a billion dollars.
