I know some of us are not into video format, but there are some channels I enjoy.
Here is one I like:
The History GuyHe's a historian who tells interesting tails from the past, I find them informative and entertaining. The videos are short, from 5 to 15 minutes. Historic documents and photos are shown, but one can just listen and still get the full story. It is a great channel to play in the background while getting mundane tasks done.
