The following two come from advertisements for Tesco.
I think this next one was from an advert I noticed for Marks & Spencer if I recall correctly.
This next, quite beautiful lady I think, appeared in an advert for Colgate toothpaste.
It really does seem like this is a definite thing now. The token redhead is now as ubiquitous in adverts as the token black person. This is most surely a good thing ..if not a little weird for redheads that aren't quite used to seeing so many of their kind up on TV screens.
Just to show this is not entirely modern though I did come across the following classy advert on Pinterest a few weeks back.
