Watching such videos makes me wish for a modern explanatory videos done in the same old style, content-rich and distraction-minimizing. Sounds like a niche nobody is willing to cover for some reason.

Related, I have similar feelings for textbooks. When I was still in school, my grandfather used to give me books for learning English and German that were from somewhere around 60s - 80s. I vastly preferred them to modern books we used in school. The old books were content-rich and created to support learning, including self-learning. The modern ones waste space with pictures, and seem purposefully designed to not allow for self-learning, and instead requiring a teacher (with a companion book).

Both old instructional videos and language textbooks are my go-to example of how market pressures can lead to destruction of actual value in the process of maximizing sales.
