I adored this show as a kid in the 1980s - watched it on public TV channel. I remembered all the episodes but forgot the name - I did all sorts of searches with key words to find it but none came up. Finally asked someone on RUclips by describing the show and that it had animotronics and primitive animation and now I am watching the again!
10:10 - that's an EMI 2001 camera on the left (with an autocue affixed to the front), dating from around 1968-1972 (which is when they were made). Many British TV companies used them and they were the workhorse of the British TV industry throughout the 1970s. The BBC were the biggest customer (indeed, it was designed primarily to fit the BBC's needs and requirements), along with about half of the ITV companies (the "big five" - Thames, LWT, ATV/Central, Granada and Yorkshire TV - along with HTV in Cardiff and Bristol and Anglia TV in Norwich). The BBC phased them out slowly, with the first being taken out of service in 1976 and the last in 1991! The aforementioned ITV companies each began replacing theirs between 1979 and 1986, with Granada being the first (throughout 1979) and Central being the last (most of theirs had been taken out in 1984, but a pair remained for use with continuity and presentation purposes until 1986). Yorkshire TV were the last ITV company to use them for regular programme use, replacing theirs in 1985, and donated them to BBC Leeds for spare parts because parts were becoming scarce by that point!
@@nivlick No, it was failing before that. The 240 lines as opposed to the 405 lines of the EMI system, having to run the film through a chemical bath to develop it between the studio and the transmitter and the poor overall quality of the Baird-only sets and camera/ studio equipment all meant that fully electronic TV was the only way forward. The fire was just the last nail in the coffin. Whatever you think of big business and its anti-social, even psychopathic, behaviour over the years, if you're launching a new technology like television from scratch, sometimes you need some proper technical and investment heft rather than just being a shoestring operation based on backwards- looking technology.
@John Ashtone yes it absolutely was. I didn't even know it was there until i stumbled across it. Ahhh back in the day when we could actually go places and do things.
There's an old, probably apocryphal story from the Cold War about American engineers first getting a close look at a Soviet military aircraft, and scoffing at it because it still used thermionic valves in its electronics instead of being all solid-state. That is, until someone pointed out that in the event of a massive electromagnetic pulse from a thermonuclear bomb going off, the instruments in the Russian plane would have been more likely to keep working whilst the solid-state electronics in its counterpart fried. By the end of the vacuum-state era, some valves ("Nuvistors") were as small as discrete canned transistors - I've seen a few TV sets that used them - and now, things are coming full circle with the recent development of the nanoscale vacuum-channel transistor...
Here we are in 2023 and I can assure you that not a singke viewer will be watching this on anything other than a high definition TV , tablet or smart phone.

I worked in a television shop when I was in high school and college in the 70's. Those old vacuum tubes, CRT's were a royal pain to work on. Today, most televisions are "disposable". They stop working, you toss them because it is cheaper to buy a new one, than to have it repaired.
0:53 - I have that same model of TV in my collection. In fact, I have two, one awaiting restoration and another that's in such poor condition it's only fit for parts. That model dates from about 1975 and it uses the Thorn 9000 chassis, introduced the same year. It was Thorn's first TV to use the Precision-in-Line ("slot mask") colour CRTs and it was the second in Britain to use that type of tube, Rank-Bush-Murphy just pipping Thorn to the post when they introduced their Z718 chassis in late 1974. The P-i-L colour CRT replaced the earlier delta-gun ("shadow mask") colour CRT that had reigned supreme in colour TV sets (apart from Sony, which used their own Trinitron tubes) from the introduction of colour TV in Western Europe in the late 1960s until being phased out in the latter half of the 1970s. Ironically, it was Thorn who were also the last to use delta gun tubes, in their sets using their 9800 chassis, made from 1978 to 1980.

I used to avidly read Tim Hunkin's cartoon strip in The Observer every Sunday, The Rudiments Of Wisdom. It did something very few people can do - it made complex things simple. Our country will be a lot more successful once we start doing this on a large scale in schools. People like me got lost on the second day of every subject, never to understand it again. We are the overlooked ones, not because we are dim, but because teaching was only ever for intelligent kids, and not for the average or below average kid like me. If only Tim Hunkin were minister for education.
The same with learning maths ! Our maths teachers were so bland and un inspiring that I fell asleep during class. When I was in my twenties I watched a Disney cartoon which shone light on all the wonderfull things you could do with mathmatics. But in a fun way which drew me in, not turn me off.
@@den264 Extraordinary mate, yet it appears few people in the teaching profession are allowed to stray from the syllabus in order to engage the entire class, before continuing with the hogwash of quadratic equations and those snot-gobbling logarythms.
This program was great, except for the fact that the history part was almost completely wrong. Zworykin never was able to get a working system up and going and the patent was eventually awarded to Farnsworth who, not even mentioned here, was actually the first person in 1927 to show a fully functional system. RCA bought Zworykin and his parents and then proceeded to try to erase Farnsworth from history, while copying his work. They ended up loosing the patent case, but it seems they were successful in changing history, at least on this show.
Some years ago I met Gerald Wells with my brother, he would not allow transistor sets in his house however he made an exception in our case and we took a video camera to his house and made a complete program about him that has never been seen
he did have some transistor sets, a few portables, in the 'radio shop recreation' room 😉 i visited a few times in the 1990s, last time in 1998, he passed away a few years ago and i've heard pretty much all the stuff in the house has been moved into the sheds out the back, with a lot sold off due to lack of space and money..
Those times we were not concern about burning down a bunch of old TV sets with lead, plastics and other pollutants. Fun times indeed. Today I would get beaten by my neighbours.
Philo Farmsworth was the inventor of electronic television. It's maddening that he's always overlooked. Zworkin's television was a very crude mechanical system.
Yes there is currently a great RUclips movie on his life and career. It illustrates hiw ruthless the American businessman can be when it comes to killing off a competitors career and life in the case of poor Philo !
21:59 onwards - that colour set is one using one of the *excellent* ITT CVC chassis (somewhere between a CVC5 and CVC9, dating it to between 1972 and 1977). That is using one of the delta gun CRTs I referred to in another comment below. Of all the TVs to go in that fire pile at the end, this ITT certainly didn't deserve to end like that!
i used to have 3 of the cvc5/8/9 series sets, plus a cvc30, and a cvc45? i think, all worked pretty well, the cvc30 being used as our main tv , with no back cover, previous owner lost it, !!, for several years in the early to mid 90s,
Today, most televisions no longer have tubes; CRT or otherwise. Now its all LCD, LED & Plasma displays. Nowadays, less people are getting Cable TV subscriptions in exchange for viewing complete TV episodes, movies & videos on the internet.
In the 70s as a kid on Halloween, I remember a house with 3 witches. My folks must have known them, it was a small town. Anyways they had a camcorder, vcr set up and I remember freaking out seeing them on TV then in person at the same time. I've forgotten a million things in 53 yrs but I'll never forget the first time I seen the magic lol
Fun Fact: Vladimir Zworykin once lived on the same street as my one-time girlfriend in Swissvale, Pennsylvania. Of course, that was 40 years before either of us were born. LOL. (Swissvale is a close by suburb of Pittsburgh. Zworykin was employed by Westinghouse.)
I think the real breakthrough which led to tv was the fundamental idea of ‘scanning’ an image, quite different to photography. Pity it wasn’t mentioned as such. Enjoyed the old-fashion approach.
I really enjoy you posting these and thank you for that. main problem is the audio is so low, I can barely hear it on my lap top. need to use amplified speakers to hear it. do not need this with other videos, just yours. It would be much more enoyable if audio was at a normal level. thanks
@MichaelKingsfordGray Then why didn't they mention it, then? In 1990, the closest you would have got to LED technology in TV sets were the small backlights used on those colour pocket TVs that used LCD screens.
@MichaelKingsfordGray It was a rhetorical question. However... Thinking back to 1990, the reason may be threefold: - The lack of availability of information about what was happening in TV technology outside of Britain until said technology was mature enough to become a mass-market product in Britain, mainly due to patriotism on the part of TV trade publications like Practical Television magazine and the annual large, thick, ruby-red Newnes TV servicing books.The researchers would have been subject to this ignorance on the part of specialist publications. This was 1989, way before the internet as we know it, so researchers would have been reliant on publications. - And on the small chance they were aware of it (certainly, people like me who were in the TV repair trade or on the periphery of it weren't aware of LED TVs until about 10-15 years after this was broadcast), the technology probably won't have been mature enough to be considered a serious contender for inclusion in the programme - it wasn't until about 2010 that (in my opinion) LED TVs began to be a serious contender in terms of picture quality for the last of the CRT TVs. - It's a 25-minute programme that's only intended to educate the average viewer and not be some specialist programme for a specialised field so even if they were aware of LED TV technology as it was in 1989, it would likely have ended up on the cutting room floor for that reason and possibly for the reason above, too. For example, notice how they don't delve too much into the benefits of in-line gun CRTs over delta gun CRTs, only giving it a passing reference in saying "owing to refinement of the tube design" when Tim Hunkin's assistant is playing about with the convergence controls on that ITT CVC5 towards the end? For the record, I've been a broadcast engineer for many years at Granada Television in Manchester and have done some editing work on programmes, too, after being made redundant and going freelance in the early 1990s - I'm using both my knowledge of TV technology during this time and thinking about what would and wouldn't have made it to the finished programme based on a list of priorities. Apart from colour pocket TVs, TVs with any kind of LED influence in the screen certainly weren't on the market here for the casual viewer to buy in 1989 because they were a long way off from being a marketable product. And as I don't think anyone working on the programme would have envisioned people wanting to watch it 30 years from then, they wouldn't have considered explaining the possibilities of future TV technology in too much detail in the programme, especially if Channel Four execs stipulate they only have 25 minutes to cover everything in the programme's brief.
@MichaelKingsfordGray I never really paid too much attention to solid-state TV technology. For me, *proper* TV truly died when 405-line TV, valves, then camera pickup tubes were replaced by so-called "superior" technology. they were the equivalent of the valve vs. solid-state audio amplifier debate - solid-state tech is technically superior, but valve pictures and sound look and sound more pleasing to the eyes and ears!
i dont think high enough brightness leds for backlights were available at this time, there were laptops with lcd panels but fluorescent backlight, and STN or early TFT technology in the screen itself with poor viewing angle, i have a couple of laptops from around the time of this program, the screen would definitely not be suitable for tv use....
And now in 2023 I am looking at the history of CRT television, on an LCD display, which is already obsolete being replaced by OLED, for even better image quality
There used to be another British documentary series that was similar to this one, in that it had some humor mixed in, but it was an hour program instead of 30mins. It was probably from the 70s or 80s, and they dealt with different subjects, and always had a starting point that led off in seemingly unrelated directions, but then everything was tied together at the end. I can't remember the name of that show....
That was "Connections" by James Burke from the late '70s (the entire series is available on youtube). Watching "Secret Life of Machines" for the first time this week, it immediately reminded me of "Connections," as well!
23:35 - I can't really tell from the poor quality of the video (as loads of TVs from the 80s had slide-out vertical circuit boards like that), but I *think* that's a set using the Rediffusion Mk4 chassis, dating it to between 1981 and 1985 (which, ironically, would have been - technologically - a little long in the tooth by then, the irony being that Tim claims in the voiceover that it's representative of a modern set for when this programme was made, around 1989!)
@@kevvywevvywoo the one with the board on the left side may be a fidelity, the board looks familiar, i repaired loads of portables, mostly grey plastic cased, using that board/chassis, usually psu blow up , occasional bad degauss posistor 😁
the one with the big 'motherboard' and several vertical boards is an itt , either cvc20 or cvc30/32, used to have a cvc30 for a few years, theres also a cvc5/8/9 shown, the one with a few valves in it, had a few of those, still got an unused 'spare' line output transformer for one..
RCA and it's engineers have to given credit for bringing tv into our homes. The RCA system of transmission and especially their system of transmitting color. The problem with the color system was finding a way that the B&W sets at the time could also receive a program that was being broadcast in color.
Indeed, they solved this problem in an ingenious way. The black and white analog signal remained, with a chroma or chrominance signal added to the carrier. This way, the telly knew what colour to add to the image.
24:39 I suppose when this was on air people were screaming "WTF?" at the end scene but now we've all been there done that with the onset of LCD, plasma, etc.
Not really - they mostly look like 1970s TV sets, which by 1990 (when this one was made) would have been considered junk. They probably got them very cheap from warehouses where knackered ex-rental stock was flogged off at dirt-cheap prices.
@@stickytapenrust6869 and now crt sets are getiing sought after ..... 😉 most of the tvs we had over the years were second hand, at least 10 years old when we got them, and still working perfectly or needing only minor repair (which i did myself)
Sigh. Back then tv was made to look great and work great. It made as furniture. Not anymore. By the way I was not alive back then and really not even a thought.
TheMonkeyFarted Back in the 50s and 60s, tv's used to be like a nice piece of furniture. Youd have a huge wooden box made of top grade, nicely finished wood, with usually mono speaker(s) in the side panels, but the actual picture tube was usually much smaller in diameter than the size of the overall box it was mounted in. So youd have a 4 foot wide, by 3.5 foot tall x 3 feet deep set, but with a picture tube that was only maybe 20" - 24" diameter(18" wide X 17" tall). They weighed a ton too! No idea how much they cost, but it was probably the equivalent to $2000 in today's dollars.....
@@HighlanderNorth1 The first TV I bought was in 1980, 22" screen and it cost $NZ 1554.38 (includes interest because it was purchased on Hire Purchase).
The irony is that tv sets are once again getting less reliable as technology progresses. An lcd screen from say the early Naughties could last over 10 years and compared with today was cheaper. A full array backlit today has an average life for many of just 4 or 5 years as the arrays fail (as we’ve found out to our cost). Oleds and plasma screens can burn out with individual led’s failing completely and ghosting. They’re getting better but still aren’t as reliable as a tv from 20 years back.
14:08 - "Gave high definition picture" It sure did. :) A resolution of around 352 × 288. If these people only knew what was going to happen just 20 years later, from the airing of this show. I'm currently watching this in 3840x2160 on a 32" 4K monitor. No more x-ray emitting CRT.
@@FunkySpunkyJunky That doesn't really make sense. 2160 implies 2K since it's about 2,000. But anyway, we do have 8K monitors now, so yes, 4000 lines :). 2160 is still impressive by 1991 standards.
@@tomservo75 yeah, i know it dont make much sense, but thats how it is. HD TV is 1080 lines and 4k is double that at 2160. You are technically correct as 8k does exist, but not on mainstream TVs that I know of. I wasn't having a dig, your point was still understood, that we now have very high def TVs that would have been unthinkable back then.

RCA bought Zworykin and his parents and then proceeded to try to erase Farnsworth from history, while copying his work. They ended up loosing the patent case, but it seems they were successful in changing history, at least on this show.
I was actually waiting to hear Farnsworth name
I wonder how much they paid for the parents?
are British stupid or what. Farnsworth is the man
@MichaelKingsfordGray the OP said RCA bought Zworykin's parents. (obviously a typo for 'patents' but I prefer the idea they bought his parents)
Yeah they never mention tesla either even though he invented alot of the things they discuss in their shows
The slotted shadowmask he shows is from the Sony Trinitron tube.This gave brighter pictures, and required fewer convergence adjustments.
Some years ago I met Gerald Wells with my brother, he would not allow transistor sets in his house however he made an exception in our case and we took a video camera to his house and made a complete program about him that has never been seen
Have you considered posting this program to RUclips?
For your own private viewing?
he did have some transistor sets, a few portables, in the 'radio shop recreation' room 😉 i visited a few times in the 1990s, last time in 1998, he passed away a few years ago and i've heard pretty much all the stuff in the house has been moved into the sheds out the back, with a lot sold off due to lack of space and money..
Those times we were not concern about burning down a bunch of old TV sets with lead, plastics and other pollutants. Fun times indeed. Today I would get beaten by my neighbours.
Philo Farmsworth was the inventor of electronic television. It's maddening that he's always overlooked.
Zworkin's television was a very crude mechanical system.
Yes there is currently a great RUclips movie on his life and career. It illustrates hiw ruthless the American businessman can be when it comes to killing off a competitors career and life in the case of poor Philo !
i am watching this on a oled monitor
21:59 onwards - that colour set is one using one of the *excellent* ITT CVC chassis (somewhere between a CVC5 and CVC9, dating it to between 1972 and 1977). That is using one of the delta gun CRTs I referred to in another comment below.
Of all the TVs to go in that fire pile at the end, this ITT certainly didn't deserve to end like that!
i used to have 3 of the cvc5/8/9 series sets, plus a cvc30, and a cvc45? i think, all worked pretty well, the cvc30 being used as our main tv , with no back cover, previous owner lost it, !!, for several years in the early to mid 90s,
definitely not! poor old things 😢

Today, most televisions no longer have tubes; CRT or otherwise. Now its all LCD, LED & Plasma displays. Nowadays, less people are getting Cable TV subscriptions in exchange for viewing complete TV episodes, movies & videos on the internet.
Watching this through a non-CRT makes me a bit sad, really.
In the 70s as a kid on Halloween, I remember a house with 3 witches. My folks must have known them, it was a small town.
Anyways they had a camcorder, vcr set up and I remember freaking out seeing them on TV then in person at the same time.
I've forgotten a million things in 53 yrs but I'll never forget the first time I seen the magic lol
I was going to throw my devices📺📱 in the river but now I've decided to burn them 😂😂🔥🔥🔥🔥🔥
Great show
Excellent
Fun Fact: Vladimir Zworykin once lived on the same street as my one-time girlfriend in Swissvale, Pennsylvania. Of course, that was 40 years before either of us were born. LOL. (Swissvale is a close by suburb of Pittsburgh. Zworykin was employed by Westinghouse.)
This Series Legend...
I think the real breakthrough which led to tv was the fundamental idea of ‘scanning’ an image, quite different to photography. Pity it wasn’t mentioned as such. Enjoyed the old-fashion approach.
10:54
it really needs to be digitally remastered
Tim is slowly getting them remastered and posted on his own YT channel for these...
Confused 🤷♂️ because, if you couldn’t record sound with the video! How did they do it then in the beginning. ?! Hmm 🤔.
The first colour tv picture shown by Baird in 1946!
Used to watch these on the Learning Channel when TLC was actually called that.
And when "The Learning Channel" actually WAS that.

That guy who was killed by an early set was killed again 2 weeks later.. and again for a quite a few times over the years.
24:34 - The first Amazon Fire TV... strange that it didn't catch on.
I really enjoy you posting these and thank you for that. main problem is the audio is so low, I can barely hear it on my lap top. need to use amplified speakers to hear it. do not need this with other videos, just yours. It would be much more enoyable if audio was at a normal level. thanks
Cool! Was the Narrow Band Mechanical Television technology ever used for smart bomb /glide bombs in the 1930's / 1940's ?
Of all the SLOM episodes, this one is probably the most dated.
Still a good watch. They had no idea that HDTV and LED would take over the industry.
@MichaelKingsfordGray Then why didn't they mention it, then?
In 1990, the closest you would have got to LED technology in TV sets were the small backlights used on those colour pocket TVs that used LCD screens.
@MichaelKingsfordGray It was a rhetorical question.
However...
Thinking back to 1990, the reason may be threefold:
- The lack of availability of information about what was happening in TV technology outside of Britain until said technology was mature enough to become a mass-market product in Britain, mainly due to patriotism on the part of TV trade publications like Practical Television magazine and the annual large, thick, ruby-red Newnes TV servicing books.The researchers would have been subject to this ignorance on the part of specialist publications. This was 1989, way before the internet as we know it, so researchers would have been reliant on publications.
- And on the small chance they were aware of it (certainly, people like me who were in the TV repair trade or on the periphery of it weren't aware of LED TVs until about 10-15 years after this was broadcast), the technology probably won't have been mature enough to be considered a serious contender for inclusion in the programme - it wasn't until about 2010 that (in my opinion) LED TVs began to be a serious contender in terms of picture quality for the last of the CRT TVs.
- It's a 25-minute programme that's only intended to educate the average viewer and not be some specialist programme for a specialised field so even if they were aware of LED TV technology as it was in 1989, it would likely have ended up on the cutting room floor for that reason and possibly for the reason above, too. For example, notice how they don't delve too much into the benefits of in-line gun CRTs over delta gun CRTs, only giving it a passing reference in saying "owing to refinement of the tube design" when Tim Hunkin's assistant is playing about with the convergence controls on that ITT CVC5 towards the end?
For the record, I've been a broadcast engineer for many years at Granada Television in Manchester and have done some editing work on programmes, too, after being made redundant and going freelance in the early 1990s - I'm using both my knowledge of TV technology during this time and thinking about what would and wouldn't have made it to the finished programme based on a list of priorities. Apart from colour pocket TVs, TVs with any kind of LED influence in the screen certainly weren't on the market here for the casual viewer to buy in 1989 because they were a long way off from being a marketable product. And as I don't think anyone working on the programme would have envisioned people wanting to watch it 30 years from then, they wouldn't have considered explaining the possibilities of future TV technology in too much detail in the programme, especially if Channel Four execs stipulate they only have 25 minutes to cover everything in the programme's brief.
@MichaelKingsfordGray You're welcome
@MichaelKingsfordGray I never really paid too much attention to solid-state TV technology. For me, *proper* TV truly died when 405-line TV, valves, then camera pickup tubes were replaced by so-called "superior" technology. they were the equivalent of the valve vs. solid-state audio amplifier debate - solid-state tech is technically superior, but valve pictures and sound look and sound more pleasing to the eyes and ears!
i dont think high enough brightness leds for backlights were available at this time, there were laptops with lcd panels but fluorescent backlight, and STN or early TFT technology in the screen itself with poor viewing angle, i have a couple of laptops from around the time of this program, the screen would definitely not be suitable for tv use....
Love the absolute environmental disaster they concocted for the end credits.
No I felt it a waste of good historic artifacts which can never be re created.
And now in 2023 I am looking at the history of CRT television, on an LCD display, which is already obsolete being replaced by OLED, for even better image quality
There used to be another British documentary series that was similar to this one, in that it had some humor mixed in, but it was an hour program instead of 30mins. It was probably from the 70s or 80s, and they dealt with different subjects, and always had a starting point that led off in seemingly unrelated directions, but then everything was tied together at the end. I can't remember the name of that show....
That was "Connections" by James Burke from the late '70s (the entire series is available on youtube). Watching "Secret Life of Machines" for the first time this week, it immediately reminded me of "Connections," as well!
Connections....
@@hellmuth26
Didn't James May (Top Gear) do a series of 'Connections' few years back?
@@hellmuth26 Connections is a bit difrent. I don't think the entire series is on RUclips :-( .
I suppose no-one puts a magnet near a screen anymore to get funky colours.
23:35 - I can't really tell from the poor quality of the video (as loads of TVs from the 80s had slide-out vertical circuit boards like that), but I *think* that's a set using the Rediffusion Mk4 chassis, dating it to between 1981 and 1985 (which, ironically, would have been - technologically - a little long in the tooth by then, the irony being that Tim claims in the voiceover that it's representative of a modern set for when this programme was made, around 1989!)
looks too modern for a mk4, even the 4A had 4 seperate pcbs, the one on screen has a switchmode power supply on the main board
@@kevvywevvywoo the one with the board on the left side may be a fidelity, the board looks familiar, i repaired loads of portables, mostly grey plastic cased, using that board/chassis, usually psu blow up , occasional bad degauss posistor 😁
the one with the big 'motherboard' and several vertical boards is an itt , either cvc20 or cvc30/32, used to have a cvc30 for a few years, theres also a cvc5/8/9 shown, the one with a few valves in it, had a few of those, still got an unused 'spare' line output transformer for one..
RCA and it's engineers have to given credit for bringing tv into our homes. The RCA system of transmission and especially their system of transmitting color. The problem with the color system was finding a way that the B&W sets at the time could also receive a program that was being broadcast in color.
Indeed, they solved this problem in an ingenious way. The black and white analog signal remained, with a chroma or chrominance signal added to the carrier. This way, the telly knew what colour to add to the image.
2:11 Skype Version 1.0 P.S. "When a repairman repairs your telly..." is not something anyone born after 1976 is likely to hear, sadly.
As kids we used to love smashing old telly screens for their implosion. Naughty but nice
Same here
Yes.
It was a mandatory rite of passage!
What about Farnsworth across the Pond?
I remmber the ones with candles in the back i mean valves or is it tubes ..jeff
In the UK, they were referrd to as valves; in the US, tubes (pronounced toobs).
Very fitting funeral pyre for the CRT television.
It's surprising how long some of the sets stayed functioning in the fire.
Wasn't the end of CRTs when that was made, though, not by a long chalk.
24:39 I suppose when this was on air people were screaming "WTF?" at the end scene but now we've all been there done that with the onset of LCD, plasma, etc.
Not really - they mostly look like 1970s TV sets, which by 1990 (when this one was made) would have been considered junk. They probably got them very cheap from warehouses where knackered ex-rental stock was flogged off at dirt-cheap prices.
@@stickytapenrust6869 and now crt sets are getiing sought after ..... 😉 most of the tvs we had over the years were second hand, at least 10 years old when we got them, and still working perfectly or needing only minor repair (which i did myself)
That madman look I his eyes when the TVs burn
this episode has a certain anachronistic autodidatism to it
Over here we have Burning Man. In the UK, there's Burning Tellys. LOL
Sigh. Back then tv was made to look great and work great. It made as furniture. Not anymore. By the way I was not alive back then and really not even a thought.
TheMonkeyFarted
Back in the 50s and 60s, tv's used to be like a nice piece of furniture. Youd have a huge wooden box made of top grade, nicely finished wood, with usually mono speaker(s) in the side panels, but the actual picture tube was usually much smaller in diameter than the size of the overall box it was mounted in. So youd have a 4 foot wide, by 3.5 foot tall x 3 feet deep set, but with a picture tube that was only maybe 20" - 24" diameter(18" wide X 17" tall). They weighed a ton too! No idea how much they cost, but it was probably the equivalent to $2000 in today's dollars.....
@@HighlanderNorth1 The first TV I bought was in 1980, 22" screen and it cost $NZ 1554.38 (includes interest because it was purchased on Hire Purchase).
This was an excellent tv series, would be great if they showed it again. Sadly UK tv now is mostly idiotic game shows and reality shows....
like secret life of machines ( not keen on reality show )
No mention of the German contribution.
not many had to worry about glasses as it was rare to be blind in today’s youths.
The irony is that tv sets are once again getting less reliable as technology progresses. An lcd screen from say the early Naughties could last over 10 years and compared with today was cheaper. A full array backlit today has an average life for many of just 4 or 5 years as the arrays fail (as we’ve found out to our cost). Oleds and plasma screens can burn out with individual led’s failing completely and ghosting. They’re getting better but still aren’t as reliable as a tv from 20 years back.
Every municipal clean up now has at least five dead TVs per street. Cheapos from Aldi, mostly, with giant screens…
Boop tube now a flat screen
Ask someone under 30 how something works and they can't explain. Computers are magic, not modulated stream of electrons, right?
14:08 - "Gave high definition picture" It sure did. :) A resolution of around 352 × 288. If these people only knew what was going to happen just 20 years later, from the airing of this show. I'm currently watching this in 3840x2160 on a 32" 4K monitor. No more x-ray emitting CRT.
The real irony is that you're watching what looks like a VHS rip in 360p on that UHD tv.
377 pixels high. Not 288.
great
What we are looking at now is not a tv😅
605 line televisions. Tell them we have 4,000 lines now!
We don't though. 4k = 2160 lines. (Twice that of 1080p)
@@FunkySpunkyJunky That doesn't really make sense. 2160 implies 2K since it's about 2,000. But anyway, we do have 8K monitors now, so yes, 4000 lines :). 2160 is still impressive by 1991 standards.
@@tomservo75 yeah, i know it dont make much sense, but thats how it is. HD TV is 1080 lines and 4k is double that at 2160. You are technically correct as 8k does exist, but not on mainstream TVs that I know of. I wasn't having a dig, your point was still understood, that we now have very high def TVs that would have been unthinkable back then.
Quite happy with my 1080p 60Hz, thank you.
405 and 625 lines

Television was invented in 1921 by an 14 year old Idaho farm boy named Philo Farnsworth
Inaccurate and nutty, typically British. I thought It was a Monty Python. Program.
May have been inaccurate but entertaining
That is funny .
Pity that Philo Farnsworth work was not recognized, and the RCA/Zarnoff lie is propagated.
24:22 ooooh how environmentally unfriendly - oooooh, should have recycled them instead, oooh what a terrible programme, ooooh, ooooh, handwringing, non PC ooooh... more handwringing....
How did we go to the Moon when TV's were looking like that?
