Yeah it super weird that while we struggle with latency in the digital world, storing anything for any amount of time is an almost impossible challenge in the analog world.
You should check out: - Core memory - Drum memory - Bubble memory - Mercury delay line memory - Magnetic type memory :P And probably many more. Remember that computers don't even need to be digital!
or electric.
CRTs are peak steam punk technology. Analog, electric, kinda dangerous. Just totally mindblowing that we had these things in our living rooms shooting electric beams everywhere. I doubt it's environmentally friendly at all, but I'd love to see some new CRTs being made.

> The image is not stored at any point. Just wanted to add one thing, not as a correction but just because I learned it recently and find it fascinating. PAL televisions (the color TV standard in Europe) actually do store one full horizontal scanline at a time, before any of it is drawn on the screen. This is due to a clever encoding used in this format where the TV actually needs to average two successive scan lines…
All PAL TVs had a delay line in them? Crazy.

I only knew about SECAM, where it’s even part of the name (Système Électronique Couleur Avec Mémoire)

Isn't "now this" just a synonym for "moving on" or "next order of business" or "apropos of nothing"? I don't think the concept of jumping to a completely new topic is something TV introduced.
It’s been a bit since I’ve read Amusing Ourselves to Death but I believe in the book the phrase ”Now this” is used disparagingly to refer to the fact that with tv you can go from a horrific news story like a local family being murdered to a completely unrelated story, both in content and emotion in the span of seconds. This doesn’t allow ample time for the viewer to process the former and essentially forces them to t…
This is interesting. John Logie Baird did in fact demonstrate something that looked like TV, but the technology was a dead end. Philo Farnsworth demonstrated a competing technology a few years later, but every TV today is based on his technology. So, who actually invented Television?
Baird did. Farnsworth invented the all-electric version (sans mechanical parts). A kin to Ed Roberts, John Blakenbaker and Mark Dean invented the personal computer but Apple invented the PC as we know it.

The invention of the "airplane" is just a simplified term for "controlled and sustained powered flight". Which the Wrights did with both controlled and powered in the 1903 Flyer. (The Wrights invented the first 3-axis control system, and designed & built the first aviation engine capable of sustained flight.) While the Wrights were first, by several years, its invention was inevitable.
> The invention of the "airplane" is just a simplified term for "controlled and sustained powered flight" Maybe? But most people think of it as "invented the airplane," and the two terms have different connotations in common use. Likewise, the title here says "television," not "real-time capture, transmission, and display of moving images" -- and similarly, I think the terms have different connotations.
There were precursors to Edison's light bulb, and people use that to denigrate Edison's achievement. But the technical reality of the Edison bulb is his bulb was practical, and the precursors were just curiosities.

We're getting awfully close to recreating CRT qualities with modern display panels. A curved 4:3 1000Hz OLED panel behind glass, and an integrated RetroTink 4K with G-Sync Pulsar support would do it. Then add in a simulated degauss effect and electrical whine and buzzing sounds for fun.
>1000 Hz This sounds like a brute force solution over just having the display controller read the image as it is being sent and emulating the phosphors.

Solid state is the superior technology for almost everything. No moving parts means more reliable, quieter, and very likely more energy efficient since no mass has to move.
Do modern hdd's last as long as the old platter ones? For me, when the SSDs fail it's frustrating because I can't open it up and do anything about it--it's a complete loss. So I tend to have a low opinion of their reliability (same issue I have with old versus new electronic-everything cars). I don't know the actual lifetimes. Surely USB sticks are universally recognized as pretty crappy. I can leave those in the sam…
My late father told me the first time he saw a TV. He was in Ann Arbor, Michigan making a sales call in 1947. When he drove in he noticed there was a huge crowd around a store window but couldn't see what was going on. After making the call he noticed the crowd was still there so he parked his car and decided to investigate. There was a black and white TV broadcasting a Detroit Tigers game in the window of a radio re…
I remember a similar story from my father, of people in the small town he was in crowding standing in the front yard of a neighbor, crowding around a picture window to look in at the first TV in town in the mid-1950's.
