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.

Except for that most of it was not.
A lot of the noise on the screen (and speaker) was affected by radiation from nearby stuff.
I’d think that nowadays, it would be even more so, with way more WiFi and mobile phone signals everywhere. Now sure, different frequencies mean they would affect less, but the cumulative effect would still be more than the CMBR.
Also, I have a flat-screen CRT at home.
