The Hilltop Coke Ad

I am a bit of an advertising and marketing history buff.  Met a few Mad Men era people while working at the world's largest marketer.  One told me that the series was not too far from sixties reality.   Also am old enough to have seen the Coke Ad in its run on TV.  Have not closely followed the series, but was intrigued by the portrayal of the arrival of computers and analytics driving marketing, which I was part of. There definitely was a creative v engineering contention.  With all that being said, the WSJ tells the real story of the Coke Hilltop Ad.  New to me.
