I dipped into some recent YouTube video uploads and found these... Here's a short (3:34 minute) video showing how typography surrounds us. Bad typography affects communication. Nothing earthshattering here, but sometimes we can use a little reminder. Then, there is this Herb Lubalin Digital Study Project video (2:47) described as a "mini-homage to a New Yorker who created the image of the American era." Finally, here's a very quick (1:08) video titled Typography - McKee Speech in Adaptation, where powerful words and a powerful delivery combine with typography (explicit language warning). Politicians who don't feel they are getting their point across forcefully enough might want to try this approach in some of their speeches.
