It’s been about 20 years since I watched cable/broadcast TV in my home. But yeah way back tvs didn’t have inputs for other devices, instead you had a box which you put in between the antenna or cable signal and your device which basically over wrote channel 3(why channel 3? I have no idea) with whatever your device was out putting. So if you wanted to play Nintendo you would change to channel 3 and see Mario or metroid.
It’s been a while since I’ve had to do a game system setup on an old TV, (like damn near 20 years) but I think you used channel 3 because it was a channel reserved for local communications, so there would never be “TV” on that channel. Your VCR connected to the TV with a coax cable, and if you wanted to have “TV” plugged in at the same time, you either needed a TV with multiple coax inputs (I think it was common to have 2, one for VCR, and one for satellite/aerial antenna) or a coax splitter. Early on, those RCA plugs weren’t built into a lot of TVs, so you needed the VCR to inject that signal onto coax for the TV. Lots (if not most/all) VCRs would let you switch the channel used in the settings, I think mainly to cover other regions where channel 3 was not standardized.
A local news station use(d? they are all digital now) channel 3, with both ota and cable. I remember using both 3 and (front) rca ‘input’ for my games.
I could be wrong, but I think that was what the convention was in the US at least.
Similar to how there is nothing “stopping” a web server from having a 192.168.x.x address, but we have a standard that blocks off those addresses to be used inside of your own network.

I remember the coax cable but did not know about channel 3 being local communication. I thought it was just convention.
Thanks for teaching me.
