Art Linkletter Talks About KGB RADIO in 1936. Yes, 1936. Long before Coe Lewis and Jim McInnes, there was ART LINKLETTER ON KGB RADIO! He was hired in 1936 to cover the San Diego World's Fair. He was just 24 years old. When you see CALL LETTERS with just 3 letters, it means that station has been around for a very very very very very long time.
