Of course radio stations need the revenues from advertising but do these radio personalities personally profit? The personalities are always talking about how "their Sleep Comfort Bed makes them feel in the morning" or how "the new Mercedes Benz is the best car they've ever owned/driven". Or how "they've saved so much money in remodeling their house" by joining some warehouse club. Do these people personally profit by advertisers who pay to advertise on their programs? If so, it seems extremely unethical.
