I really liked this quote Martin Weigel posted from Stephen King (the marketing guy, not the horror filmmaker) on how marketing companies must evolve:
Marketing companies today… recognize that rapid response in the marketplace needs to be matched with a clear strategic vision. The need for well-planned brand-building is very pressing. At the same time they see changes in ways of communicating with their more diverse audiences. They’re increasingly experimenting with non-advertising methods. Some are uneasily aware that these different methods are being managed by different people in the organisation to different principles; they may well be presenting conflicting impressions of the company and its brands. It all needs to be pulled together. I think that an increasing number of them would like some outside help in tackling these problems, and some have already demonstrated that they’re prepared to pay respectable sums for it. The job seems ideally suited to the strategic end of the best account planning skills. The question is whether these clients will want to get such help from an advertising agency.
