Having just finished my software-defined analog video decoder[0], I've gotta say, my mind is thoroughly blown by just how much of an engineering achievement television must've been at the time when it was invented. It must have also been the first ever communication system to have backwards compatibility.

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.

It's worth deep diving into how analog composite broadcast television works, because you quickly realize just how insanely ambitious it was for 1930s engineers to have not only conceived, but perfected and shipped at consumer scale using only 1930s technologies.

Being old enough to have learned video engineering at the end of the analog days, it's kind of fun helping young engineers today wrap their brains around completely alien concepts, like "the image is never pixels" then "it's never digital" and "never quantized." Those who've been raised in a digital world learn to understand things from a fundamentally digital frame of reference. Even analog signals are often reasoned about as if their quantized form was their "true nature".

Interestingly, I suspect the converse would be equally true trying to explain digital television to a 1930s video engineer. They'd probably struggle similarly, always mentally remapping digital images to their "true" analog nature. The fundamental nature of their world was analog. Nothing was quantized. Even the idea "quanta" might be at the root of physics was newfangled, suspect and, even if true, of no practical use in engineering systems.

What do you mean "had"? I just turned mine off a minute ago. I am yet to make the transition to flat screen TVs but in the mean time, at least no-one's tracking my consumer habits.

Not through your TV, but they see you driving to the last Blockbuster tho

I wish.

It doesn’t begin at the transmitter either, in the earliest days even the camera was essentially part of the same circuit. Yes, the concept of filming a show and showing the film over the air existed eventually, but before that (and even after that, for live programming) the camera would scan the subject image (actors, etc) line-by-line and down a wire to the transmitter which would send it straight to your TV and in…

Our station had an art department that used a hot press to create text boards that were set on an easel that had a camera pointed at it. By using a black background with white text you could merge the text camera with a camera in the studio and "super-imposed the text into the video feed. "And if you tell the kids that today, they won't believe it!"

It's kind of amazing the sort of hoops people needed to jump through to make e.g. the BBC-1 ident: https://www.youtube.com/watch?v=xfpEZDeVo00

'Steampunk' means no electricity. You need to come up with another term. Analogpunk, maybe?

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?

I think it would be pretty uncontroversial from the technological point of view, but then, the first "real" TV broadcast would be the 1936 Olympic games...

I still only have CRT, No matter how much i browse shopping sites or visit showrooms, i cannot make up my mind buying newer tv, lcd, led, plasma, oled etc, so much new technologies have arrived but i have'nt tried them for TV Yet as of today My tv's have gone through real stress test in real life unlike factories During childhood, we had our tv Switched on in morning 4:00 till 22:00 at night, constantly being watched…

I think it was because old TVs already had wide gamut, so sRGB meant a significant reduction. It never was "contrast" as such. Anything made today is vastly better than any CRT.

I remember when we organized our lives around television. On Saturday mornings it would be cartoons (including the first full-CGI television shows, Reboot and Transformers: Beast Wars), Wednesday evenings would be Star Trek: TNG, Fridays would be the TGIF block of family shows (from early-to-mid-90s USA perspective here). It felt like everyone watched the same thing, everyone had something to talk about from last nig…

> but I do have a feeling of missing out on that shared connection lately Mass media isolates individuals who don't have access to it. I grew up without a TV, and when TV was all my neighbors could talk about, I was left out, and everyone knew it. While other children were in front of the television gaining "shared experience", I built forts in the woods with my siblings, explored the creek in home made boats, learne…

It’s funny because when social media first came out, I also start to feel I had shared experiences and I wasn’t weird

Diamonds on a dung heap. For every good series which we love there are dozens of terrible/forgettable ones. A shame since TV has so much potential as a medium.

Well, A-Team was objectively terrible but I have a nostalgic connection to kids shows like that, Knight Rider etc. In retrospect Bay Watch was an effective CPR training tool at unprecedented scale. I would be hesitant to pass judgement.

The A Team was objectively terrible, but I think it had a good main cast and never pretended to be anything it wasn't. Ditto Knight Rider.

I think Glen Larson was behind both of these.

Baywatch was often terrible, but many of us watched for other reasons.

I think this is likely to be true for every artistic creation that requires lots of capital and widespread human coordination. Ultimately for a TV show to be great many, many things have to go right, and much of what could go wrong happens after the money is spent and the air date is already assured. I'm grateful we've had so many great things, certainly far more than I'll have time to watch in my life. But I'm not a…

I think the problem nowadays is that there are so many channels and so much space to fill. TV runs 24/7 now on hundreds of channels. In many cases, it isn't worth the while of a small channel to make an expensive programme as they would lose money.

Sometimes, the "wrong" programme is the hit. I know the History Channel started off with serious documentaries (some of them excellent quality) which not enough people watched. They then tried Nazis and Ancient Egypt, but it seems to be "Ancient Aliens" which is their biggest hit. Its version of history is questionable, to say the least.
