As photographers and videographers, the resolution of our displays is crucial to our ability to see the detail of our work. That's why it's a treat to see how far we've come since the advent of displays.
Even for someone who grew up playing DOS games on a VGA monitor, the 4K world of today is still astounding to me. Seeing this video really underscores just how crazy technology has become: in less than a century, we've gone from 30 lines of resolution in a tiny glass dome to displays with so much resolution that our eyes literally cannot discern the individual pixels. For some perspective, the 4K standard has 72 times more vertical lines than the paltry 30 lines the Televisor had.
The Televisor is an example of a mechanical television, a device whose generation and recreation of a signal relied on some sort of mechanical device, normally a rotating disk with carefully placed holes in it. Contrast that with the standards of today, where data is read and displayed electronically. I always enjoy seeing historical demonstrations of technology; I think it's very cool to see the pioneers of our modern world and to see how things have evolved over time.
