Reasons for preferring listening to "up to date" podcast episodes

Not sure this makes a good post for this site, but I am looking for use cases which would make the podcasting model still viable in nowadays times in view of the following considerations. I wanted to know, from a usability perspective, what would make a user want to stay up to date and always listen to the latest podcast episode, as opposed to any episode. I ask because I am used to YouTube videos, address usually, i just click on any video I am interested in, and don't care about what date it was published. So, my question is, what makes podcasters care about the episode date? I mean, the only scenario I can think of is if it was about news or politics, in which case users may almost never want to download or stream and listen to old stuff.

Anyone have any other use case ideas?

Thanks.
