A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. Avoid politics
    1. NEW RULE as of 5 Nov 2024, trying it out
    2. Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
    3. Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct-----

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.

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.

I'm talking long before digital channels existed. (In the US anyway)
