While you are responsible to your clients for sales results, you are responsible to consumers for the kind of advertising you bring into their homes.
David OgilvyI avoid clients for whom advertising is only a marginal factor in their marketing mix. They have an awkward tendency to raid their advertising appropriations whenever they need cash for other purposes.
David OgilvyA good advertisement is one which sells the product without drawing attention to itself.
David OgilvyIt has taken more than a hundred scientists two years to find out how to make the product in question; I have been given thirty days to create its personality and plan its launching. If I do my job well, I shall contribute as much as the hundred scientists to the success of this product.
