A podcast is like internet talk radio that you can download and take with you on your phone or whatever and listen to on the go. Or you can just listen to it online if you want. If you get into listening to podcasts there is so much good content out there on just about any subject you want. You just need a podcast app like Apple Podcasts or Podbean or (the one I use) Podcast Republic. You search for the podcast, subscribe to the podcast, it is downloaded each time a new one comes out, and you can listen on the go or at home. You can also just download individual episodes to try them out. Some popular traditional radio shows also put out podcasts so that people can listen when they have time on their own.
I did one called This JW Life where I told my story as a JW and the process of leaving. Now I do one called Shunned (which I announce on here when I put out a new episode) where I help others to tell their stories of leaving the JWs (along with other cults). Apparently telltale does one called "telltale" (just look for his symbol that he uses on here to post). There are other exjw podcasts like Critical Thinker, JW Community, JW podcast, and occasionally another new one will pop up here or there.
I also like true crime shows, business and entrepreneurial podcasts, lots of story podcasts where people tell real life stories, financial podcasts, etc.
