The new episodes stay free for a few years, then go behind a paywall. Right now for free are the series on the Persian Empire, on WW1, the first two episodes on the Japanese Empire in WW2 (3 should be out someday soon), and a couple of stray one-offs. All recommended. It’s a happy day when a new Hardcore History comes out, but it only seems to happen every 6 months or so. The guy does a lot of research going into each episode.
Sounds good. I’ll check it out.
