BRADENTON, Fla. — There are scores of them out there – independently produced, nationally distributed, specific subject talk shows. You know which ones I mean. The ones you regularly hear on weekends or very early in the morning or quite late at night – health programs, legal advice, financial advice, pet care, news analysis, gardening, etc. Most of them are quite good. The program hosts are knowledgeable on the subject matter and are articulate. And the shows are well produced and professionally presented covering subjects that are important, informative and valuable to listeners.
