First, the advertising and editorial functions of the Journal are totally independent. Although I as editor have a general notion of the magnitude of our advertising revenues, I am totally ignorant as to how much comes from which company. From time to time, I examine ads for tastefulness and appropriateness, but it has never occurred to me to figure out which companies buy more advertising space. Therefore, I lack the information base to experience the subconscious influences about which Drs. Capehart and Holsinger are concerned.
