Plethora of Math History Videos
Consider the history of mathematics. In the past, MathNEXUS has reviewed many resources related to this interesting history...websites, books, videos, etc.
Then I discovered Pinterest's collection of videos on the History of Mathematics. A lot of options....most of them videos of lectures offered by either mathematicians or math historians (note: There is a difference!).
My suggestion is to just browse and listen in on a video...and if it gets too dry...skip ahead in that video or move on to another one. You will find something of interest.
