There's also audio dramas. Niche but good. They're a narration like books, but they are made for the audio medium.

The problem I've found with audio books is that they were made to be read - and it shows. It requires a lot of focus to listen to an audio book even if it was done well, and it feels "clunky" and "janky" in a way. I can't white put my finger on what's wrong with it but it feels wrong to me. Audio dramas are generally easier to listen to, sometimes they use epistolary formats to make them easier to separate into episodes, and they have a lot more attention on things like the background music and conveying parts of the narration through audio itself, rather than "writing" (so just reading something aloud). I find them fascinating, because they're really fun to listen to and they seem like the compromise between a book and a movie.

"The Magnus Archives" is great.
