write a a?biographya of a significant advertising campaign, either contemporary or historic. Tell the history of that campaign, and you will dissect it. How did it work? What were the key elements? What was the strategy? In what way was the campaign innovative and what were the key creative ideas? What kind of impact did it have? You must subject the campaign to critical review and the illumination of theory. Where possible provide the operational details as well eg media mix, media scheduling and budgets.
