The owners of the AM station, at 1250, and then 1590, were constantly searching for a format that would be successful . . . with little luck. When I first showed up at KZOK, in the fall of 1974, KTW-AM was across the hall doing talk radio with personalities like Greg Palmer, Wayne Cody, Bill Russell and Skip Brown (who went on to some fame as Aaron Brown). Here in 1975, Seattle Times, radio columnist Vic Stredicke explores the latest experiment. An experiment that would last for less than two years. In 1977, 1590 AM became KZOK-AM.
