I don't have that many I've kept up with consistently, but there are 4 regulars- On Being, Making Sense, Radiolab, and 99% Invisible. I will skip episodes of any of them if the description sounds like a snoozer ;)
I've a big fan of the PBS SpaceTime series on YouTube. Ok, that isn't a podcast, but it is a regular series that *could* be a podcast if it didn't need visual content. It's very podcast-like in having regular content that fits a specific topic and is extremely well-produced. A video podcast?
Video podcasts are absolutely a thing. Or at least they used to be.
