  • 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.

  • 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.

  • 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.

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

  • CRTs were fairly common until the early-mid 10s

    I'd say born after 2008ish aren't likely to be familiar with them, except seeing the odd one in their grandparents bedroom

  • Our cable provider (my parents like cable TV) had analog channels even like 2 years ago, but they started encrypting everything which required purging the analog selection.

    This sucks. At worst analog would be grainy, digital just keeps cutting out in worse conditions.
    I wish there was also still analog OTA TV for this reason. Much easier to pick up usable signal.

  • You can still hear it on the radio. Although most of the noise floor is probably man made.
