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, if they had watched any HBO show, they kind of saw it !

[–] mlg@lemmy.world 2 points 1 hour ago

Dude Flatscreen HDTVs were expensive even in 2008, and cable actually got worse for higher price so most people were hooked into local broadcast.

If they ever watch Poltergeist they'll know it's the TV people trying to get out.

[–] PagingDoctorLove@lemmy.world 1 points 18 minutes ago

They haven't?

I have a TV from ~2010 that still gives me static when something isn't connected.

[–] r_deckard@lemmy.world 5 points 1 hour ago

The sky above the port was the colour of television, tuned to a dead channel...........

[–] melvisntnormal@feddit.uk 3 points 59 minutes ago

I still see it sometimes when connecting my Steam Deck to my TV

[–] DrownedRats@lemmy.world 11 points 1 hour ago (1 children)

People born before 2000 think older technology just evaporated the minute the millenium ticked over.

[–] LovableSidekick@lemmy.world 3 points 25 minutes ago* (last edited 24 minutes ago)

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.

[–] bonn2@lemm.ee 9 points 1 hour ago

2001 here literally grew up with CRT static, you have your years a bit off there.

[–] Socsa@sh.itjust.works 11 points 2 hours ago (2 children)

It really isn't though. It is thermal noise.

[–] RememberTheApollo_@lemmy.world 2 points 55 minutes ago

Could it not be both?

[–] LovableSidekick@lemmy.world 3 points 19 minutes ago* (last edited 18 minutes ago)

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 it's a phenomenon of flatscreens. I found something that said it was "similar to snow on analog TVs" - so apparently 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.

[–] Blackmist@feddit.uk 12 points 3 hours ago

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.

[–] HEXN3T@lemmy.blahaj.zone 6 points 3 hours ago

Say that to my three CRTs. I was born in 2003.

[–] Bytemeister@lemmy.world 7 points 3 hours ago (2 children)

Cosmic microwave? Is that what you are calling "ants in a snowstorm" these days?

[–] bitwaba@lemmy.world 1 points 2 minutes ago

Salt and pepper fighting.

[–] kingvolcano@lemmy.world 4 points 2 hours ago (3 children)

"War of the Ants", where I'm from (sweden).

[–] pyre@lemmy.world 2 points 1 hour ago

ok Sweden wins this one

[–] shadow_wanker@lemmy.world 2 points 54 minutes ago

Ask your friend which side is winning, say you're rooting for the black ants, then turn off the TV and claim victory.

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 it amusing

[–] LANIK2000@lemmy.world 12 points 6 hours ago (1 children)

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.

[–] Fredselfish@lemmy.world 2 points 5 hours ago (1 children)

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.

[–] Car@lemmy.dbzer0.com 2 points 3 hours ago (1 children)

Some TVs may project fake static.

Just because OTA broadcasts are digital doesn’t mean you are stuck with all or nothing. You can definitely have poor signal and see or hear something other than what was intended. Doesn’t manifest as analog static, but depending on your decoding and error correction schemes, you can have cut audio, frozen frames, iframe inconsistencies, and stuttering.

[–] piccolo@sh.itjust.works 2 points 2 hours ago* (last edited 2 hours ago)

No digital is all or nothing. What you are describing is some digital packets making it through and the algothrim is designed to accept some packet loss and has error correction. Its more complicated then i make it out, but thats the jist of it.

It is nothing like analog thats being drowned out by background radiation.

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 if you're not inputting video from some other device. Or 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.

[–] tkk13909@sopuli.xyz 13 points 7 hours ago

Dude I was born after 2000 and this is firmly planted in my memories. Maybe people born after 2010 haven't but 2000?

[–] pineapplelover@lemm.ee 3 points 5 hours ago

I have actually, we had a big old crt tv way back when

[–] ViscloReader@lemmy.world 3 points 5 hours ago

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

[–] Sam_Bass@lemmy.world 5 points 6 hours ago

Many likely haven't seen a channel sign off for the night with a test pattern up til they come back on

[–] Sylvartas@lemmy.world 5 points 6 hours ago (1 children)

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

[–] dch82@lemmy.zip 3 points 5 hours ago* (last edited 5 hours ago)

To be fair though, many kids nowadays have never seen a save icon as autosave is now practically everywhere. For example take anything on an iPad or other touch device.

[–] possiblylinux127@lemmy.zip 32 points 9 hours ago (2 children)

It is entirely possible for people born after 2000 to have grown up with CRTs.

DAE remember that movie White Noise? The climax was fucking horrifying and I have to admit that it haunted me for quite a while.
For better or worse, kids today probably won't get it.

[–] pineapplelover@lemm.ee 2 points 5 hours ago

Is it worth scarring myself to know the context?

[–] Barzaria@lemmy.dbzer0.com 10 points 7 hours ago

"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.

Maybe not directly on their TV set, but there are more than enough references to it in TV and film media 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.
