xpanding for the past few years, to the point where major authors from Gladwell to Sanderson are releasing some of their new pieces first as audiobooks, and only later sending them to print (if they send them to print at all). The way people are talking, this is a new thing, the next big thing to accompany the podcast moment.
Since I don't listen to very many of these, I don't have a lot of basis for comparison, but one (and by one, I mean the only) podcast that I listen to more or less consistently is Dan Carlin's Hardcore History. I've alluded to it in review posts before for some of the historical works that I've read, but I decided it would be worthwhile to provide a genuine recommendation. Even if you're not interested in sitting down and actually reading something like Herodotus's Histories, you can still gain much of the knowledge and historical context from listening to these podcasts.
