Does anyone remember how, back on old broadcast TV, text on the screen would make the rest of the video funky and even make a buzzing sound? Anyone have one of those amazing youtube videos that explain that?

CRTs just make that sound. You begin to not hear its frequency as you get older. Also the text over the screen was sometimes an additional signal stream so how it handled interlacing it was kinda weird iirc. The lack of buzzing is you getting older. I'm sorry.
No no no, I know the CRT frequency noise you speak of, and you're right, I don't hear it anymore, but this was a very different buzzing that changed based on what was on screen. The CRT hum I could hear outside of someone's house when the TV was on

The closed captioning I swear was just another additional frequency getting interlaced into the signal for the image and sound causing extra noise to the audio. I dont know if anyone has tried to really explain this. Maye it also used extra hardware?
