It is interesting, both within my own environment and further afield, how cynical marketing is viewed. Getting ones message across is ever more difficult in a diverse world with expanding markets. What might appeal to one person in one country will not appeal to somebody else in another, for example Facebook in Germany, English chips in Holland, etc.
Of course we should all be marketing, whether it be a personal, or professional level. Maybe if more of us did that, we would need to have such departments. Everybody would be marketing. Still every organisation has to define what their message is.
