Formats change but ads lag

From a Times staff writer

Country KKGO-AM (1260) and classical KMZT-FM (105.1) switched frequencies and music formats Monday, but the advertising on the two stations wasn’t as quick to follow.

During the morning hours, an ad for an L.A. Philharmonic concert was heard amid the country tunes on what is now KKGO-FM, while the classical strains on the new KMZT-AM contained a commercial with Tanya Roberts hawking a Las Vegas promotion.
