Its obvious that I love all things cool. Someone that studies the concept Cool is Dr Lauren Gurrieri [AKA Dr Cool] she says the origin of Cool can be traced back to the Yoruba people of Africa and their word Itutu [great word]. Dr Gurrieri was recently interviewed by a radio station in Australia, this podcast is interesting listening if you are into that kind of thing. The first reference to cool in advertising was in a campaign for the Volkswagen Beetle in the 1950's called 'Think Small' [see Ad below]. There are other interesting facts [listen to the podcast] but the COOLEST BY FAR is the fact that the origin of 'cool' is African. No wonder I'm crazy about it. Coolness!
