One may remember or forget these messages but briefly one takes them in, and for a moment they stimulates the imagination by way of either memory or expectation. The publicity image belongs to the moment. We see it as we turn a page, as we turn a corner, as a vehicle passes us. Or we see it on a television screen whilst waiting for the commercial break to end. Publicity images also belong to the moment in the sense that they must be continually renewed and made up-to-date. Yet they never speak of the present. Often they refer to the past and always they speak of the future.
Publicity is usually explained and justified as a competitive medium which ultimately benefits the public (the consumer) and the most efficient manufacturers - and thus the national economy. It is closely related to certain ideas about freedom: freedom of choice for the purchaser: freedom of enterprise for the manufacturer. The great hoardings and the publicity neons of the cities of capitalism are the immediate visible sign of "The Free World."

Publicity is the culture of the consumer society. It propagates through images that society's belief in itself. There are several reasons why these images use the language of oil painting. 
Oil painting, before it was anything else, was a celebration of private property. As an art-form it derived from the principle that you're what you have. 

Publicity is, in essence, nostalgic. It has to sell the past to the future. It cannot itself supply the standards of its own claims. And so all its references to quality are bound to be retrospective and traditional. It would lack both confidence and credibility if it used a strictly contemporary language.
Capitalism survives by forcing the majority, whom it exploits, to define their own interests as narrowly as possible. This was once achieved by extensive deprivation. Today in the developed countries it is being achieved by imposing a false standard of what is and what is not desirable.
