Poole in 1952, originating from Catalina Island off the coast of California. Known as "The Catalina Island Station", Poole knew KBIG would have wide coverage of Southern California by broadcasting the station's directional signal across ocean water. KBIG was heard from Santa Barbara to San Diego, including the large audience in Los Angeles. The station became popular as it presented an island theme and scheduled music, news, and commercials on a different sequence from his competitors. "We knew if you changed stations during a commercial, you would always find music on K-BIG," Poole claimed.
