That reminds me. They did used to broadcast software over teletext over TV https://teletext.mb21.co.uk/gallery/ceefax/telesoftware/

There was also a system where some TV screen pixels were used to send data, but I'm struggling to remember how you were supposed to get it into the computer.

I suspect that you needed to build some light sensor with a serial cable, that you held to the screen, but I'm not sure.

This was in the Netherlands, not sure if it was done elsewhere.

That looks interesting, but it's not ringing any bells.
