When I was a kid, I definitely remember a more history-centric focus on the History Channel, although I remember even then (early 2000s) that they seemed to lean pretty heavily on WWII documentaries. It seemed every time I switched to the channel, one would be playing. It's more or less been the way it is for the last decade or so, though.
I've had a life-long fixation on WW2, so I loved the in-color war documentaries. I just remember the history channel also covering documentaries on (real) ancient history and other historic topics. I miss that era of the channel, I want to see that again instead of ancient aliens, ice road truckers, and pawnstars.
