“The heart of our business is the creative product. Many clients do their own marketing, buy their own media, have superb research. But is there any advertiser with an excellent creative department? Creative people prefer an agency environment, the challenge of many products, the stimulation of other disciplines, all concerned with advertising. Advertisers need agencies for the creative product best produced by agencies. We never forget that fact.
