Have you done your marketing today?

The first thing that comes to my mind when I hear the term marketing is a word that is related to advertising, business and commerce. A colleague once said to me that she went to do some marketing. I came to realise that she meant shopping for grocery in the supermarket, only after dwelling further onto the subject. But this is something that is rarely used in such context based on my own personal experience.

My question is: Is the usage of the term marketing in the literal sense still appropriate in the English speaking community?

The word "marketing" used in the sense of "visiting a market to purchase goods" was mostly displaced by the word "shopping", in the sense of "visiting a shop to purchase goods", around the time in particular places when open-air markets were replaced by enclosed, privately owned shops. It seems economics and government policies are responsible for the change of meaning. Perhaps the word "marketing" was a bit orphaned when it was drafted by the management profession.

Dictionaries of English include plenty of attestations that the word "marketing" did indeed commonly include visiting a market to purchase, as well as sell, products, and there are attestations that native speakers (only) still use the term that way.

In a related way, "shopping" a product (such as a script or idea) in the sense of seeking to sell or promote it, seems to have subsequently replaced "marketing" that product when the term "marketing" took on its current, more specialized management science meaning.
