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
    • 3.1) NEW RULE as of 5 Nov 2024, trying it out
    • 3.2) Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
    • 3.3) 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

People born after 2000 have never seen the cosmic microwave background on their TV set. (startrek.website)

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.

Technically, it's not about the display technology, but instead about the signal/tuner. More specifically if it's analog or digital. Some modern TVs still have analog or hybrid tuners for backwards compatibility and regions that still use analog, so they can display static. For instance, in Ukraine we finished the switch to digital TV only a couple of years ago. If your TV had no digital tuner (as was the case for many) you had to buy a DAC box. Retirees/pensioners got them for free, sponsored by the government.
