Making money with podcasting

My sister-in-law visited over the holidays and had one simple question: how do you make money with podcasting?? She knows a few podcasters are sponsored, but couldn’t imagine me getting enough sponsorship to make much of an income.

My answer: teach others to become podcasters with a purpose. That worked in the early days of website construction: I taught web design at the community college level, and also taught my web design clients how to maintain their sites.

Now I’m thinking about building a course teaching sales professionals how to get in front of almost any decision-maker through podcasting. Does anyone on the forum know a salesperson who might be interested?
