Most company branded podcasts have a well defined host, whether that is a member of the communications team, a senior leader, or an outside expert with audio credentials. It's interesting to see how a show navigates a model of not having a singular host or group of hosts:
The show from the consulting company's travel sector has some episodes that are a common structure of an internal expert interviewing other guests, whether from the company or externally. They have a quick intro of the guests from an (unnamed) narrator but otherwise jump straight into the interview. It's an interesting trade-off between more structure from a dedicated host and their model that makes it easier to swap in different expert interviewers in different topics.
They also have a really unique episode about consumer travel that combined two things I've haven't seen melded together. They recorded the bulk of the interview at a live panel at the SXSW conference. It's tricky to get great audio in those environments, and there tends to be some downtime during Q&A and transitions. The upside is that it's readily available thought leadership content.
The episode's topic is “Boarding Now" about emerging travel trends. And before they get into the panel segment, it starts with a set of acted out vignettes of future travel scenarios. It's a fun, sonically rich format that built some fun energy before getting into the structured conference segment.
