Do Wait Wait Don’t Tell and Fresh Air? They call themselves podcasts, even though they also air on NPR.
I like that kind of podcast because it tends to be tighter, better edited.
I enjoy Jamie Jeffers’s The British History Podcast, which is about (you guessed it) British history. He starts with pre-historic Britain and the arrival of the earliest Celtic peoples, and from there takes a deep dive into the history and culture of Britain. Very deep: the most recent episode is number 488, and he’s only gotten to the year 1100.
Jamie is a witty and likeable narrator, and he goes into great detail about many of the various Anglo-Saxon kings and rulers that most histories tend to skip over in their eagerness to get to Alfred the Great. Have you ever heard of kings named Penda, Ida, Caedwalla, or Oswy? Neither had I, before this podcast.
Just to note, for the OP: Fresh Air is an interview show; Wait Wait… Don’t Tell Me! is a comedy game show. Both of them originated, decades ago, as NPR radio programs, but are now also offered to listeners in podcast format.
