There are basic rules to all 'Talk Radio Shows', and if you follow a few simple ones you can create an engaging radio show. It is important to know that it is not just good content alone that makes a show work, but how you deliver it also, from both a unique and interesting angle. That and good interaction with guests and callers does not hurt.
First off, the discussion material ......show content should usually be topical. If it isn't related to current events and what is going on in culture, then you better have a good hook to give the audience a reason to stick with you through the segment. Second, the segments... a talk segment needs to be organized and tight. This is where a well prepared show outline is essential. It will help you keep on track and have some relevant notes to better make your points. Third, the delivery..... you are a combination of entertainer and educator, so the material must be engaging and not too wordy. Think about macro views vs. micro ones, plus it helps the momentum of a program.
