I used to follow this blog — I believe it was somehow associated with Slate Star Codex? — anyways, I remember the author used to do these experiments on themselves where they spent a week or two only reading newspapers/media from a specific point in time and then wrote a blog about their experiences/takeaways
On that same note, there was this great YouTube series called The Great War. It spanned from 2014-2018 (100 years after WW1) and followed WW1 developments week by week.
The people that did the Great War series (at least some of them, I believe there was a little bit of a falling out) went on to do a WWII version on the World War II channel: https://youtube.com/@worldwartwo
They are currently in the middle of a Korean War version: https://youtube.com/@thekoreanwarbyindyneidell
The Great War series is phenomenal. A truly impressive project.
