Channel 3 is just the preset on your TV set, or these days the EPG position
Channel 9, Channel 7 etc. were the VHF frequencies their transmitters broadcast on. TV sets then didn't have presets, they had tuning dials like a radio. These days we use UHF channels 21-69 but they're not referred to on air, with national networks and now digital multiplexes it would take too long and there's not much point
US TV stations are still generally one transmitter per station and so still do refer to themselves with VHF and UHF channel numbers, hence [url=http://en.wikipedia.org/wiki/KCBS- TVC]CBS2[/url] or ABC25
As to why it became '3' on everyone's sets, well the other two stations had '1' and '2' in their names! (cue lots of posts about how everyone's TV presets were configued...)
Wow, thanks for that. Around when did the companies start referring to the preset 3 and drop the VHF frequency?
Probably the essential thread to ask this question, but when did TTTV Channel 8 and Granada Channel 9 etc all become Channel 3? Was there a reason why different ITV stations were on different channels?
