If you want to establish yourself as a thought leader, you need a strategy that includes multiple different formats. A podcast makes for a great way to show off your experience in a field. It is long-form and will allow you to discuss topics in enough depth to show the breadth of your knowledge to an audience. You'll be able to have interesting guests on that engage the interest of the listener or viewer. Because podcasts are such a long-form media, they are easy to break down into smaller segments or component parts that extend their benefit to you.
