uhhh, yes i have? I’m pretty sure my younger cousins have lol

They haven’t?
I have a TV from ~2010 that still gives me static when something isn’t connected.
If they watch Poltergeist they’ll know it’s the TV people trying to get out.
Well, if they had watched any HBO show, they kind of saw it !
I still see it sometimes when connecting my Steam Deck to my TV
Dude Flatscreen HDTVs were expensive even in 2008, and cable actually got worse for higher price so most people were hooked into local broadcast.
The sky above the port was the colour of television, tuned to a dead channel…
People born before 2000 think older technology just evaporated the minute the millenium ticked over.
LOL like when the black and white world suddenly got colorized. My grandpap told me about them old days - when the lawn, the sidewalk and the sky were just different shades of gray.
2001 here literally grew up with CRT static, you have your years a bit off there.
I was about to say, i think we had a CRT till about 2010. My grandma still has one upstairs so even my youngest cousins still grew up with it.
Umm… I had a CRT until 2009 and even sold it to someone.
Was it just me or has anyone seen or make out patterns while staring at it? I sometimes found in amusing
It really isn’t though. It is thermal noise.
Random radio sources, but a small part of the signal is CMB. I wasn’t sure what you even meant by thermal noise but I believe you’re talking about flatscreens. I found something that said it was “similar to snow on analog TVs” - so I gather there’s a difference.
Funnily, Google AI says, “In the 1940s, people could detect the CMB at home by tuning their TVs to channel 03 and measuring the remaining static after removing other sources. This allowed them to prove the Big Bang before scientists did.” So they had that going for 'em, which is nice.
“Thermal Noise” is a phenomenon where everything makes EM noise, just from thermal energy.
If you were to put such a TV in a faraday cage, with an RF termination, you would see something similar. Because noise is inherently part of the circuitry and amplifiers.
Could it not be both?
Last time I thought about static I wondered why colour TV didn’t show colour static.
Turns out the colour signal was on very specific frequencies, and if it wasn’t present, it would assume it was a black and white signal and turn off the colour circuit.
Cosmic microwave? Is that what you are calling “ants in a snowstorm” these days?
Salt and pepper fighting.
“War of the Ants”, where I’m from (sweden).
Ask your friend which side is winning, say you’re rooting for the black ants, then turn off the TV and claim victory.
ok Sweden wins this one
Ant races
I have actually, we had a big old crt tv way back when
As person born after 2000, I used to play a lot of games on them Wii and GameCube mainly. The image and responsiveness really felt different. I do kinda miss them
Many likely haven’t seen a channel sign off for the night with a test pattern up til they come back on
Also, a lot of kids don’t have the slightest idea of what the “save” icon in their apps represents. They just know it’s the save icon because it’s everywhere
To be fair though, many kids nowadays have never seen a save icon as autosave is now practically everywhere
DAE remember that movie White Noise? The climax was fucking horrifying and I admit that it haunted me for quite a while.
For better or worse, kids today probably won’t get it.
Is it worth scarring myself to know the context?
2002 here, we still had such a TV. For quite a while actually, since we never upgraded and just started using phones and computers instead. It became my console monitor.
Yeah OP full of shit. My three sons all born after 2000 have seen this. Hell my flat screen will show snow if I turn it to antenna and there nothing for single to pick up. Also I have console tv for our old gaming systems so they seen that as well
They also know how a vcr works and what a payphone is. We are not that far removed from that technology. Hell my middle son 17 has a record collection and cds. Also we have the cassette audiobook version of Stephen King Dolores Claiborne.
Modern Tv project fake static when there is no siginal because of fimilarity. OTA broadcasts are all digital, either you get a siginal or you dont.
Maybe not on their TV set, but there are more than enough references to it in TV and film that it’s still known almost universally.
Everything from old beloved films to Modern period shows. Its literally an overused way to establish the narrative isnt taking place in the present.
Tube TV’s remained in common service well into the 2010’s. The changeover from analog to fully digital TV transmission did not happen until 2009, with many delays in between, and the government ultimately had to give away digital-to-analog tuner boxes because so many people still refused to let go of their old CRT’s.
Millions of analog TV’s are still languishing in basements and attics in perfect working order to this very day, still able to show you the cosmic background, if only anyone would dust them off or plug them in. Or in many retro gaming nerds’ setups. I have one, and it’ll show me static any time I ask. (I used it to make this gif, for instance.)
In fact, with no one transmitting analog television anymore (probably with some very low scale hobbyist exceptions), the cosmic background radiation is all they can show you now. Unless you have one of those dopey models that detects a no-signal situation and shows a blue screen instead. Those are lame.
Amateur radio operators are indeed allowed to transmit analog NTSC television in the UHF band. It’s most commonly done on the 70cm (440MHz) band, and a normal everyday 90’s television is all you need to receive the signals. You’d tune to what would have been cable channels 57 through 61. The use cases for this have decreased in recent years; for example you used to see hams using amateur television to send video signals from RC aircraft or model rockets, now that’s done with compressed digital video over something like Wi-Fi and doesn’t require a license. But, it’s still legal for hams to do.
I think my mom still uses the last CRT TV that I had. Gave it to her when I bought my first 720p HD TV, as the old CRT was better than her old TV. Later on I also gave her that HD TV but she still has the CRT too.
Dude I was born after 2000 and this is firmly planted in my memories. Maybe people born after 2010 haven’t but 2000?
“The sky above the port was the color of television, tuned to a dead channel.” - William Gibson, Neuromancer
Gibson describes the static as metallic, silvery gray in an interview.
“The sky was the perfect untroubled blue of a television screen, tuned to a dead channel.” - Neil Gaiman, Neverwhere
I remember the white static myself.
My grandpa always just called it “The ant races”
I saw on ‘how it’s made’ a conveyer belt of a bunch of apples and it reminded me of the TV static the way they all rolled around forming random structures like a crystal. From then on I always think of apples on a conveyerbelt when I see static.
I was born after 2000 (though not too long after) and this is actually one of my core memories. I think about the sounds of the static and the sound of the CRT turning off.
Also, we had a really old tv in our basement till at least 2008 that had no remote, just knobs and I remember messsing with the “hue” dial all the time trying to figure out how it worked.
The only reason that tv worked so late is that we had a black box connected to the antenna which I later learned was converting the digital signal to analog for the TV.
Also, you’ve just reminded me that I remember the switch from analog to digital. Specifically, I remember watching Elmo talking with some adult on TV about the change. Now I really want to find that video. I think the guy was wearing a suit had short dark hair and glasses. I also think the background was pinkish purple. I want to know how accurate my memories from so long ago are. (I’ll add the link to the video in an edit if I can find it)
Opening line of Neuromancer doesn’t make much sense any more "The sky above the port was the color of television, tuned to a dead channel.”
“The sky above the port was blue, with a grey rectangular box with writing saying ‘No signal found.’”
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
That’s not background, that’s a free channel that showcases a polar bear in a snowstorm.
