I’m sure there were other consoles that did it, but the one I remember is the NES; it had a physical switch on it for channel 3 or 4, and you had to have your TV tuned to the respective channel to get the game to show up. As to why that was necessary on a technical level, I’m not sure. But it was a thing you had to do.
