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