While it may seem a little cliché, another way to refine your show’s concept is to ask the standard Who, What, Where, When, and Why questions.
Who – Who is going to watch the show? Who is going to host the show?
What – What topics will the show cover? What genre or format will it use?
Where – Where will the show be recorded? A studio? On location?
When – When will the show come out? Weekly? Monthly?
Why – Why would a viewer subscribe to the show? Why would they come back for another episode?
