Duggan hosted television shows on KCOP-TV, KTLA and KTTV, and wrote a newspaper column for the "Los Angeles Herald-Examiner". In early 1965 Duggan was hired to do the morning drive show on KBLA-Burbank (1500 AM) as part of the station's new top 40 format, but lasted only a couple of months. He then moved over to KLAC ("Two-Way Radio") to host a talk show and stayed for four years. In 1967 he commuted between Los Angeles and Chicago for 10 months to tape a program for Chicago television.
