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.
