Literally "Coast to Coast AM"! The host was named Art Bell. The show is still on the radio with the host George Noory.
The show is a bit different now, I don't listen to it often so I could be wrong but it seems to me that Art Bell always had a bit of a smirk or wryness, while Noory just comes across completely serious. Also with Art Bell it was simpler times, with the more entertaining aliens and cryptozoids and MiB. Now there is a lot more of the modern political deep state/Q/child trafficking stuff. Religious fundamentalism always showed up a lot in the "conspiracy theory" world. Before it would be things like how aliens are actually angels or something and signs of the rapture. Now you regularly hear guests talking about how God chose a certain person to clear out the demonic deep state, so there's a more disturbing undercurrent.
