The static on old CRT TVs with rabbit ears was the cosmic microwave background. No one in the last 25 years has ever seen it.
Well, not really. The cosmic microwave background radiation was a tiny fraction of that noise. What everyone saw was mostly thermal noise generated by the amplifier circuit inside the TV.
CRTs was in use well into the 2000s
Even before the 2000s they started showing a blue screen instead of static.
That wasn’t just a digital or flat panel thing.
But of course old sets were around for a long time.
My memory of the exacts here are fuzzy, but I think this depended on whether or not your TV picked up digital signal, analog, or both. I remember around that time we had a TV that would pick up static on some channels and have a blue input screen on others.
It’s definitelly an analog over the air TV thing.
The way digital works you would either get a “No signal” indicator (because the circuitry detects the signal to noise ratio is too low) or squarish artifacts (because of the way the compression algorithms for digital video are designed).
I’m talking long before digital channels existed. (In the US anyway)
What are they hiding from us?!
Yeah I was still using a CRT as recently as 2012. I think OP means analogue TVs.
Technically, it’s not about the display technology, but instead about the signal/tuner. More specifically if it’s analog or digital. Some modern TVs still have analog or hybrid tuners for backwards compatibility and regions that still use analog, so they can display static. For instance, in Ukraine we finished the switch to digital TV only a couple of years ago. If your TV had no digital tuner (as was the case for many) you had to buy a DAC box. Retirees/pensioners got them for free, sponsored by the government.
Yeah, my youngest sibling has definitely seen CRTs. My niblings probably haven’t, though.
I thought they were teaching it in all the schools? /s
Do you think CRTs just magically disappeared after the turn of the millennium?
Don’t you still see this when using an OTA ATSC tuner on a newer LCD display? I thought this was a function of the signal generation and not the display technologies.
Can confirm.
It actually was a pretty rapid switch where all the CRTs disappeared
They lied to us. The real Y2K was the CRT rapture.
I think they’re more likely to have been scrapped than other old tech.
They’re bulky, and mine was too heavy to get out in the attic. I still have my ZX Spectrum and Amiga, but the CRT needed for lightgun games is long gone.
Well to be fair at some point most/all CRTs showed a blue screen instead of static. So it’s possible someone born in 2000 never saw the snowy display.
As someone born in 2000, I’ve personally seen it and I think most people around me did. Maybe someone didn’t, though.
they have to watch HBO shows to compensate
Surely you mean the much worse “Max”.
By the way, the picture illustrating the post isn’t actually displaying the real thing - the noise in it is too squarish and has no grey tones.
TV static in recent movies and shows that are set in the past almost always instantly pull me out of the narrative because no one seems to be able to get it right and some are just stunningly bad. It’s usually very subtle, so much so that I’m not sure I could even describe what’s wrong. Makes me feel old to notice it.
I think the problem is because CRT displays didn’t have pixels so the uniform noise which is static was not only uniformely spread in distribution and intensity (i.e. greyscale level) but also had “dots” of all sizes.
Also another possible thing that’s off is the speed at which the noise changes: was it the 25fps refresh rate of a CRT monitor, related to that rate but not necessarily at that rate or did the noise itself had more persistent and less persistent parts?
The noise is basically the product of radio waves at all frequencies with various intensities (though all low) with only the ones that could pass the bandpass filter of the TV tuner coming through (and being boosted up in intensitity by automatic gain control) and being painted along a phosphorous screen (hence no pixels) as the beam draw line by line the screen 25 times per second so to get that effect right you probably have to simulate it mathematically from a starting point of random radio noise and it can’t be going through things with pixels (such as 3D textures) to be shown and probably requires some kind of procedural shader.
It is entirely possible for people born after 2000 to have grown up with CRTs.
It is, but those late model CRTs often had a lot of digital circuitry that displayed a solid color on channels with nothing on them. Unless there was a much older CRT around, they never would have seen it.
Most of the CRTs are going to be older
No one in the last 25 years has ever seen it.
I mean you can still find a CRT today and turn it on if you like, they’re less common for sure, but they’re still around if you’re looking for one
Kids born after 2000 aren’t looking for one
Well that’s a lie, I know an early 20 year old who’s into retro games and has definitely been to an arcade with CRTs in the past year or so. It’s not a stretch to imagine he’s seen static on one
i know i am.
I had three different ones growing up. The first 2 were black and white and the last one was color. All found on the side of the road.
I find one every once in a while, on the side oft the road aswell, unfortunately some idiot usually sprayed graffiti on it for some dumbass Instagram post, or I have no room at my place ATM.
Dude I’d kill for the opportunity to get my hands on a half-decent CRT
You’d be surprised, some people born in the 2000s want them for the retro factor now
I bought a plasma in 2009 that would show static if I turned it to cable channels without cable plugged in. Plasmas were susceptible to burn in and since I would game a lot I could see health bars etc start to burn in after a while. Whenever that would happen I would turn it to the static screen - making each pixel flip from one end of the spectrum to the other rapidly like that would actually help remove the burn in.
The sky above the port was the color of television, tuned to a dead channel. - William Gibson, Neuromancer
One of the most beautiful opening lines to a novel.
If you remember that it was written in 1984, the color is obviously black and white static. If you don’t think about the year, you might be lead to believe it is blue.
Literally 1984
The opposite of a Bulwer-Lytton!
One of the most beautiful opening lines to a novel.
Abundantly clearly not.
This is it:
“It was a dark and stormy night; the rain fell in torrents—except at occasional intervals, when it was checked by a violent gust of wind which swept up the streets (for it is in London that our scene lies), rattling along the housetops, and fiercely agitating the scanty flame of the lamps that struggled against the darkness."Torrents >> TV
Uh, no:
“The man in black fled across the desert and the gunslinger followed.”
“She strutted into my office wearing a dress that clung to her like Saran Wrap to a sloppily butchered pork knuckle, bone and sinew jutting and lurching asymmetrically beneath its folds, the tightness exaggerating the granularity of the suet and causing what little palatable meat there was to sweat, its transparency the thief of imagination.”

My family had several tvs that did this until around 2013
Born 2000, yes i have. So has my younger brother
yeah i have
On a CRT? Sure, probably a lot haven’t seen it. On a modern TV? Still possible for some - mine does this if I hit the channel button rather than volume accidentally.
Depending on the TV it’s likely simulated noise at this point
That noise is horrible; why would someone simulate it rather than just show a blue screen?
I am doubting myself now after not being able to quickly find a verified source but I’ve worked with lots of smart TVs and seem to recall Samsung or LG models using this simulated effect. It would have had to have been simulated since there was no signal coming in, and I recall the pattern being noticably pseudo random.
As for why: I have no idea! Maybe just for user familiarity reasons, since a lot of people grew up with that kind of analog feedback that the antenna wasn’t getting a signal.
Take what I said with a grain of salt, though, since like I said I wasn’t able to quickly verify it. It’s a vivid but ambiguous memory, though, since I also thought it was strange
As for why: I have no idea! Maybe just for user familiarity reasons, since a lot of people grew up with that kind of analog feedback that the antenna wasn’t getting a signal.
This is exactly why. Preventing screen burn-in may be a tiny peripheral reason also, but providing a familiar experience to chronically myopic and cranky users (i.e. boomers) is probably the bigger one.
That’s not background, that’s a free channel that showcases a polar bear in a snowstorm.
