Television is 100 years old today

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?

AndrewDucker•1h ago
There were a great many small breakthroughs over time. Where you draw the line is up to you.

For what it’s worth, Philo Farnsworth and John Logie Baird were friendly with each other. I was lucky to know Philo’s wife Pem very well in the last part of her life, and she spoke highly of Baird as a person.

David Sarnoff and RCA was an entirely different matter, of course…

The article has a photo of a plaque putting Baird's death in 1946, less than 40 years old.

What happened?

roarcher•35m ago
He was 57, born in 1888. Died of a stroke.

I had a communications theory class in college that addressed "vestigal sideband modulation," which I believe was implemented by Farnsworth. I think this is a critical aspect to the introduction of television technology.

VSB came later. From https://www.tvtechnology.com/opinions/hdtv-from-1925-to-1994

In the United States in 1935, the Radio Corporation of America demonstrated a 343-line television system. In 1936, two committees of the Radio Manufacturers Association (RMA), which is now known as the Consumer Electronics Association, proposed that U.S. television channels be standardized at a bandwidth of 6 MHz, and recommended a 441-line, interlaced, 30 frame-per-second television system. The RF modulation system proposed in this recommendation used double-sideband, amplitude-modulated transmission, limiting the video bandwidth it was capable of carrying to 2.5 MHz. In 1938, this RMA proposal was amended to employ vestigial-sideband (VSB) transmission instead of double sideband. In the vestigial-sideband approach, only the upper sidebands-those above the carrier frequency-plus a small segment or vestige of the lower sidebands, are transmitted. VSB raised the transmitted video bandwidth capability to 4.2 MHz. Subsequently, in 1941, the first National Television Systems Committee adopted the vestigial sideband system using a total line rate of 525 lines that is used in the United States today.

Farnsworth…

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.

You should read about the invention of color television. There were two competing methods, one of which depended on a spinning wheel with colored filters in it. If I remember correctly, you needed something like a 10-foot wheel to have a 27-inch TV.

Sure enough, this was the system selected as the winner by the U.S. standard-setting body at the time. Needless to say, it failed and was replaced by what we ended up with... which still sucked because of the horrible decision to go to a non-integer frame rate. Incredibly, we are for some reason still plagued by 29.97 FPS long after the analog system that required it was shut off.

Why is an integer frame rate better?

Originally you had 30fps, it was the addition of colour with the NTSC system that dropped it to 30000/1001fps. That wasn't a decision taken lightly -- it was a consequence of retrofitting colour onto a black and white system while maintaining backward compatibility.

When the UK (and Europe) went colour it changed to a whole new system and didn't have to worry too much about backward compatibility. It had a higher bandwidth (8mhz - so 33% more than NTSC), and was broadcasting on new channels separate to the original 405 lines. It also had features like alternating the phase of every other line to reduce the "tint" or "never twice the same color" problem that NTSC had

America chose 30fps but then had to slow it by 1/1001ths to avoid interference.

Of course because by the 90s and the growth of digital, there was already far too much stuff expecting "29.97"hz so it remained, again for backward compatibility.

> but every TV today is based on his technology.

Philo Farnsworth invented the cathode ray tube. unless you're writing this from the year 2009 or before, I'm going to have to push back on the idea that tv's TODAY are based on his technology. They most certainly are not.

shellac•33m ago
No, Braun invented the cathode ray tube.

1897 Ferdinand Braun invents the Cathode Ray Tube dubbed "Braunsche Röhre"

https://en.wikipedia.org/wiki/Kenjiro_Takayanagi

'Although he failed to gain much recognition in the West, he built the world's first all-electronic television receiver, and is referred to as "the father of Japanese television"'

He presented it in 1926 (Farnsworth in 1927)

However father of television was this dude:

High definition is nearly 90 years old? I guess their definition of high is quite low by more modern standards.
ronsor•1h ago
Going from 30 lines to 300 lines is a big leap!
anthk•54m ago
Cinema was "HD" by design. So, in some way, 35mm movies are HD quality and predate PAL and NTSC standards.
tosti•12m ago
Sure, but that's not TV.
racl101•1h ago
Thank you Mr. Farnsworth.

Philo Farnsworth did make considerable contribution to television with his image dissector, but he didn't make the first TV. He was the first TV patent holder in the US though.

Odd we never adapted to it.

Video has a strange hypnotic power over most people and messages seem to bypass normal mental defenses.

I'd say we did, you need more and more for the same effect.

And 100 years ago my great-aunt and grandmother (both RIP) were little kids and my great-grandmother, born in the 19th century and which I knew very well for she lived until 99 years old, was filming them playing on the beach using a "Pathe Baby" hand camera.

I still have the reels, they look like this:

https://commons.wikimedia.org/wiki/File:Films_Path%C3%A9-Bab...

https://fr.wikipedia.org/wiki/Path%C3%A9-Baby

And we converted some of these reels to digital files (well brothers and I asked a specialized company to "digitalize" them).

100 years ago people already had cars, tramways (as a kid my great-grandmother tried to look under the first tramway she saw to see "where the horses were hiding"), cameras to film movies, telephones, the telegraph existed, you could trade the stock market and, well, it's knew to me but TV was just invented too.

Inspired one of my absolute favorite Zappa grooves.

I am the Slime

https://www.youtube.com/watch?v=iiCQcEW98OY

I am gross and perverted

I'm obsessed and deranged

I have existed for years

But very little has changed

I'm the tool of the Government

And industry too

For I am destined to rule

And regulate you

I may be vile and pernicious

But you can't look away

I make you think I'm delicious

With the stuff that I say

I'm the best you can get

Have you guessed me yet?

I'm the slime oozin' out

From your TV set

You will obey me while I lead you

And eat the garbage that I feed you

Until the day that we don't need you

Don't go for help, no one will heed you

Your mind is totally controlled

It has been stuffed into my mold

And you will do as you are told

Until the rights to you are sold

That's right, folks

Don't touch that dial

Well, I am the slime from your video

Oozin' along on your livin' room floor

I am the slime from your video

Can't stop the slime, people, look at me go

I am the slime from your video

Oozin' along on your livin' room floor

I am the slime from your video

Can't stop the slime, people, look at me go

The Baird vs Farnsworth debate reminds me of similar discussions in tech. The first demo rarely becomes the dominant standard.

What strikes me is how fast the iteration was. Baird went from hatboxes and bicycle lenses to color TV prototypes in just two years. That's the kind of rapid experimentation we're seeing with AI right now, though compressed even further.

> Television, he notes, has introduced the phrase "now this", which implies a complete absence of connection between the separate topics the phrase ostensibly connects.

This idea is why I always take media with a grain of salt. The decontexualization makes it easy for people to be reactive towards something, that isn’t logical

Eg “now this is why <insert person or group> is good/evil”

People call me the devils advocate when I point out these nuances but I just think we need to be much more critical when forming and holding opinions.
