It is important here not to confuse publicity with the pleasure or benefits to be enjoyed from the things it advertises. Publicity is effective precisely because it feeds upon the real. Clothes, food, cars, cosmetics, baths, sunshine are real things to be enjoyed in themselves. Publicity begins by working on a natural appetite for pleasure. But it cannot offer the real object of pleasure and there is no convincing substitute for the pleasure in that’s pleasure’s own terms. The more convincingly publicity conveys the pleasure of bathing in a warm, distant sea, the more the spectator-buyer will become aware that he is hundreds of miles away from that sea and the more remote the chances of bathing in it will seem to him. This is why publicity can never really afford to be about the product or opportunity it is proposing to the buyer who is not yet enjoying it. Publicity is never a celebration of a pleasure-in-itself. Publicity is always about the future buyer. It offers him an image of himself made glamorous by the product or opportunity it is trying to sell. The image then makes him envious of himself as he might be. Yet what makes this self-which-he-might-be enviable? The envy of others. Publicity is about social relations, not objects. Its promise is not of pleasure, but of happiness: happiness as judged from the outside by others. The happiness of being envied is glamour.
