I just recently discovered Joseph Fink's serialized podcast WELCOME TO NIGHT VALE last week. As of writing, I'm listening to episode 22 of 97, each podcast is about 25 minutes long on average and a new one is released every two weeks.
I'm loving the podcast, it has a humorous urban fantasy vibe to it and there's some level of consistency in the vignettes. As each episode gets curioser and curioser, I also find myself getting more and more invested in the townsfolk and Night Vale in general.
Here's a sample in case you're curious, and if you have any more podcast recommendations for me that's similar to this, please leave a comment below, I'd love to check it out.
