We went from the twin lead coming from the antenna on the roof, to the coaxial stapled along the outside wall, coming in through a hole in the wall near the TV and connecting to a box, which connected to the antenna in. Then the VCR comes in and the TV got a coaxial in. Then we had the RCA component in on the TV, along with RGB. That’s where CRT input ends.

There’s the TOSLINK, but I think that was only for audio hardware.

Then HDMI, and probably other ones I’m forgetting.

I was there for all of it. Including the rabbit ears antenna on “portable” CRT TVs. And, the Sony Watchman.
