Herb is the sales manager at radio station WKRP, having been with the station since 1966. The station's poor performance prevents Tarlek from securing deals with major advertising agencies (as it was, even if the station were successful, the agency employees personally loathed Tarlek anyway). Tarlek is able to keep the station financially solvent through the subprime advertising market, courting unconventional advertisers (often this involved airing ads from companies that catered to a very old demographic, such as Shady Hills Rest Home, Gone With the Wind Estates, and Ferryman Funeral Homes). He also was not beneath recruiting less reputable advertisers to buy airtime on WKRP, such as Dave Wickerman, whose "diet pills" turned out to be a legalized form of speed. Herb's most reliable advertising client is Red Wigglers (the "Cadillac of Worms"), though the owner of Red Wigglers, Harvey Green, pulled his commercials off WKRP after the Religious Right threatened a boycott of the station's advertisers ("a lot of religious people fish"). Several episodes of the series involve Tarlek and Andy Travis personally courting companies to advertise on the station.
