Comment on Are you too young to remember these?

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

Thanks for teaching me.

  It’s not the case. We had WISC-TV, the CBS affiliate, on channel 3 in our area. I seem to recall that one could switch between channel 2 and channel 3 on the Atari RF modulators, and later, VCRs could switch between channel 3 and channel 4. I think they used 2 and 3 because those were the first two channels, and the FCC wouldn’t allow two adjacent channels in the same area, so one of the two would always be unused for everybody. (Oddly, there was no TV channel 1.)

    I had a nes and that switched between 3 to 4. My next console was n64 which had the 3 wires you see in the original post

  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.
