The smallest responsive version of the logo says "coke", rather than "coca-cola", which I've not seen before. I couldn't see any use of "coke" by itself, when used for "diet coke" they use a different style: http://www.amodelrecommends.com/wp-content/uploads/2011/02/d...

If you actually looked through the images page you will find that when the single word "Coke" is used (most notably on the Diet Coke can, but also on occasional promotional items) it's in a much more modern serifed font, rather than the script font used for the classic Coca Cola logo.

None of the results on that page or image results show Coke in the classic font.
