Innovation is key. Consistent principles are important but innovation down the line will not only keep things fresh for your audience, it will draw in new audience members. Don’t be afraid to change things up as long as the essence of your program stays the same. When you do innovate though what you want to make sure is that you are actually progressing and excelling. Whether that means presenting information in a more creative or efficient way, or offering different viewpoints on the typical episode story for more depth. It is all in an effort to reward your fans for sticking around and invite new fans with the “cool, new” things you are doing.
