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.

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

    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.

      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.

        “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.

    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.

    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.

          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.

            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.

    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. For example take anything on an iPad or other touch device.

    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.
