Problem:
What do you or I or anyone need to be informed about regarding Coke?
Personally, as a card-carrying member of the Human Race since the 60's, I am as informed as I will ever need to be about Coke.
Coke mass-markets, so there is no new or targeted market to entice.
There is probably not a sole in the world who does not recognize Coke, and, if there were, it would likely be a very, very small number, not big enough to justify the massive dollars that Coke spends on advertising.
So, why does Coke advertise?
