Why did old TVs require that the channel be on 3 before accessories like VCRs and game consoles could work on them?

Anyone who grew up in the CRT era of TVs remembers that you had to turn the channel to 3 before you turned on the VCR or game console. Otherwise, the picture would not work. Why was this so necessary?

Edit: woah this blew up while I wasn’t looking! Thanks for the replies!

Here’s a cable TV company [“Keep It On 3”](https://www.youtube.com/watch?v=QYOImTAV4Zg) customer education series of commercials from 1995, produced so that people with cable boxes didn’t tie up the Customer Service lines, and trigger truck rolls, just because they didn’t have their damn TV sets on Ch 3.

OK, I made this. I went nuts. Managers gave me this assignment, they expected just a single commercial, perhaps with a service tech, wearing hardhat, standing in front of his van, saying: “Please keep your TV set on Channel 3.”

Instead they got this.
