Podcast Episode Type
Podcast Episode Type Definition - What is a Podcast Episode
Serials refer to a series which has an over-arching theme or plot, and each episode is tied together by this plot or theme. In contrasts, shows which are episodic are made up of individual episodes, each with its own self contained plot or theme. In the case of podcasts this could be the difference between a podcast with a fictional theme, characters, or backstory, versus a product review based podcast.
