Perhaps because it was so short and sweet, I still remember the definition of marketing given by my business school professor in a lecture hall many years ago.   He said that the essence of marketing is to “find a hole and fill it”.

I’m reminded of that lecture every time I come across a granary tree.  They’re a funny looking structure, a snag (dead tree branch) or sometimes a post honeycombed with neatly drilled holes, each hole about an inch wide and stuffed with an acorn.
