What about the audio aspect of podcasts? We provide speaker turn information, along with audio features that capture this information, such as pitch, allowing future research to consider elements like emotion, humor, or sarcasm

...Discussion of George Floyd was widespread across categories, with 21% of podcasts saying his name in at least one of their episodes in our time-period. Furthermore, discussion of racial justice peaked quickly around George Floyd but transitioned to a longer-lasting focus on Black Lives Matter

A network figure where podcasts are connected by edges if they have hosted the same guest. Color is assigned based on self-ascribed podcast category labels. Layout is determined with the force-directed Yifan-Hu algorithm. Podcasts in the same category appear closer.

How do the creators of podcast content exchange ideas and form communities? We find that the Business, Sports, and News categories form communities through shared guests, whereas other large categories such as Religion and Society do not
