This was before podcasts, but I used to listen to this guy Art Bell on AM radio at night. (for those that don't know, AM frequency has very poor quality but the signals can travel far). Art Bell's Coast to Coast show would talk about aliens and the supernatural.. And there was always some controversy going on with Art, that he couldn't give you the full details of yet. So there was always this lingering mystery that the CIA or some government crackdown was happening to Art for revealing dark secrets.
Me and my sister would get baked on weed far out in the woods and listen to Art's live voice crackle through the speakers, revealing the latest government alien conspiracy. He'd have callers call in with their wacko stories. It was a great experience and I haven't had it since those times.
