Do you know what a "podcast" is? A podcast is simply an audio recording (typically in MP3 form), where you talk about a certain subject, and submit them to the podcast directories. Now the biggest podcast directory on the internet is iTunes. Almost every famous person who has a show or a popular Youtube channel uses podcasts to market their products and services. Even my favorite financial expert Suze Orman uses podcasts to teach her listeners tips and advice on how to be financially free. When I first got started making podcasts for one of my old businesses along while ago, I would use a webcam to record myself on video, and then extract the audio from the video file to create the podcast. Now granted, the software that I was using to turn my videos into podcast wasn't too good - but it was all that I had at the time.
