If you only eat one bagel today, this is the bagel.
Summary
The author received a handheld emulator console as a Christmas gift and while configuring CRT TV shaders, realized they lacked understanding of how analog CRT televisions actually worked. This led them down a research rabbit hole where they discovered the impressive technology behind CRT TVs - how electron beams hit phosphor-coated glass screens, create images through scanning patterns, and are controlled by magnets. The author expresses amazement at the analog technology that seems almost sci-fi compared to modern digital displays.

I'm used to 'pixels are three little lights combining rgb colors', which doesn't work here, so I went on a rabbit hole and let me tell you, analog TVs are extremely impressive tech.
Getting an electron beam to hit a glass, making the chemicals on it spark, covering it in a 'reading motion' for hundreds of lines, and doing that 60 times a second!
And the beam is oriented by just careful usage of magnets. It sounds super sci-fi for...
