This video only solidifies the fact that the CRT is one of the most complex and sophisticated inventions in human history. Every part, the tube, the shadow mask, the electron gun, the deflection yoke. All works of art. And they did it at a price and scale that nearly everybody could afford one. Now they're left to rot on roadsides and considered worthless. What travesty.

And their TVs. They were one of the first to bring out modular sets. Those were the easiest to fix. There were 4 modules and in the service truck, we'd just carry the modules. Go into the house, analyze the issue, change the faulting module, take the old module as "trade-in" and head back to the shop. There, we'd pop the failed module into our jig, troubleshoot and repair the issue for the next call.

Manufacturing CRTs today would still be labor intensive, regardless of how far automation has advanced. This is because CRTs have many individual complex components that require great precision to manufacture. Modern TVs (LCD, OLED) are completely different technologies, which in many ways are much easier to manufacture. Light and cheap plastic defeated heavy and expensive glass. New TVs (LCD at that time) literally immediately gained an advantage over CRT in such characteristics as dimensions, weight and energy consumption. But in terms of overall picture quality (not just pixel detail), LCDs and OLEDs have only recently begun to approach CRTs. And in some aspects of the image, modern TVs still cannot surpass CRT. For roughly the same reason, PDPs (plasma) also left the market. It was a very high-quality, but too complicated and too expensive technology compared to new plastic panels (which are basically just a lot of tiny LEDs).

Insatlled quite a few of these when I was 17 - but only after "rejuvenating" the old tube had failed! They represent most of the weight of the TV set. Good old Radio Rentals would squeeze the last hours out of a tube before replacing it. Tubes were also dismantled and "re-gunned" to give them a second life. It's a good job this documentary was made on 16mm film which has outlived this whole technology. Now we can still watch that film, scanned to video and delivered down an old phone line to appear on you tube. A lot of very early video tape "films" are now lost and those that remain are very low resulution.

I'm gonna guess that it was basically because basic cathode ray tubes had already been in manufacture for decades, and their fundamental principles were well-documented, and well-known by all sectors of technology involving visual display. CRTs are relatives of vacuum tubes, which were themselves the predominate transistor technology of the era. In other words, certain technology was already the underpinning--the known quantity--such that it just made *sense* to experiment and refine CRT technology in that technological context. The sort of miniaturised componentry involved in LCD technology just hadn't been achieved at the time of television's nascence and establishment, so it wouldn't have made any financial sense to want to R&D a totally new 'ballpark' of technology when this perfectly good CRT/ vacuum tube technology already existed. I would presume that in order for these super-thin, super-light, cheaper-production LCDs to proliferate, certain milestones, breakthroughs and contexts had to have been reached/ realised. TL; DR Background tech standards will direct upcoming tech.

I saw a flat black and white LCD back in 1986 at Philips, which would be placed upon a overhead projector, so you could beam a large version of your computer image on a wall, but as this was only a relative low resoluiton (400 lines or so) and the switching speed of the LC was not that fast, it never saw the commercial market. Also because everyone was used to Colour TV, going back to a black and white LCD TV would not sell even in those days.

easy answer, you cant have a matrix LCD without semiconductors, the only semiconductor existing in the time of first CRT screens was a vacuum tube. If there would be some liquid crystal display in that time (they started in 1960s), then the matrix would need wall sized "electronics" to drive it. In this light first CRTs appear like microelectronics... 😁 And just to bring you in time perspective, first larger public TV network started in 1930s in Nazi Germany.

@@null140 I think the difference is mainly a scale-one. With CRTs, the complexity is at a macroscopic level (how to manage high voltage, convergence, geometry, sync, how to create color, the shadow mask or aperture grill, signal demodulation, etc...). With LCDs, LED and OLED, the complexity is at microscopic levels (how to create an acceptable crystal stucture which switches fast-enough to allow high-enough framerates without ghosting, how to create sufficiently bright light sources to shine through the crystal layer without having a huge power draw, how to create blue LED, how to create theses LEDs small enough to fit millions of them onto a single screen, how to manage all these LEDs or crystals at once with a powerful-enough processor, etc...). Overall LCDs, LED, QLED and OLED are far more technologically complex than CRTs while being significantly cheaper to make. It's kind of incredible when you think about it how cheap the technology we use nowadays is considering the complexity of the inner-workings. Just the making of a cheap calculator CPU is already a kind of black magic.

so interesting. i wonder if there are any of these still new old stock left today or every single one has been broken?

Various types still turn up in the US every now and then. Of course, we had so many TV shops. You can even find new old stock black and white ones…

It baffles me that we as humans figured out how to firstly, harness electricity and use it for lights, but then figured out a way to project images on a screen like this. Even just in black and white is crazy.
