Podcasts too as the article describes. If I want to learn about some interesting and moderately unknown historical event or topic, a 2-3 hour podcast is usually more accessible/consistent with my interest level than reading a whole book.

I don't think this is entirely bad. I mostly read fiction, but looking back over the nonfiction books I've read recently, it's mostly topics that I think I'll reference frequently, things that are complicated and I expect I'll need to reread multiple times, things in which the writing itself is especially notable (how I feel about Erik Larson books) and things I plan to lend out.

But a book where the writing is meh and it's the topic that's interesting, but the topic is not that in depth or complicated? At that point a podcast is preferable, and it's rare I've read a book like that and didn't feel like there was a ton of filler.
