It can work well for a branded company podcast to be the amalgamation in one feed of more than one distinct ongoing series, united in a broader theme or simply being associated with the same organization. And there are now more and more vertical-specific podcast production companies getting traction by demonstrating their expertise making shows for many clients in the same industry.

Pharmacy Podcast Network

This show from the production company of the same name is essentially a hybrid of both. The company makes dozens of shows for pharmacy clients, and they created this feed that brings them together. (I assume the shows have dedicated, individual feeds as well.) They are impressively prolific, with nine episodes released the week that I listened to it. And during the episode they mentioned that they have 42 hosts of individual shows.
