I remember seeing the Carlton logo while hearing a Carlton announcer in the Midlands on 27th October 2002 (the night before the Celebrity idents began) on TV saying "Well, this is it. After more than 15 years with you here in the Central region, this is my very last announcement. So, from me, Kevan Brighting, all this remains for me is to say goodnight and goodbye."
Carlton didn't broadcast in the US
I was watching television in the Midlands, UK, not the USA.
