I came across a lot of marketing definition in the last 25 years. Some of them are so pretentious and not easy to digest to become obnoxious.
However, the marketing description I prefer the most was given by, an all most unknown copywriter, John E. Kennedy at the beginning of the last century, and it defines marketing as “Salesmanship in print”.
Nowadays, this definition can be updated as: “Salesmanship on media” which is not as impactful as the original definition, but it reinforces the idea that the work of a marketer didn’t change much, it just become more sophisticated thanks to technology, data and researches, but has the same goal: to increase revenue and sales while building a brand.
