Again, kind of a point for NPR given at least they do have an expert talk for like, 3 to 15 (or longer for some specially podcasts) and never angry. Less or no ads, although they still have sponsors. Plus if it's really grim, they give a content warning (although it's not like they show snuff videos like cable news does).

Also local news affiliates, they fill time with silly fluff like how a bake off is going or local pet adoptions. But that still has the ads.
