This is one of several papers presented at a Federal Trade Commission Symposium on Media Concentration. It expresses views of the National Association of Advertising Publishers regarding problems that publishers of advertising shoppers and free newspapers encounter from chain-owned newspapers. Shoppers and free newspapers are described and differences from regular newspapers are noted. The growth of competition between shoppers and newspapers and the effect of concentration of ownership on paid newspapers is explored. It is suggested that in towns where the chain newspaper faces no competition, advertising rates soar; whereas in towns where the independent shopper offers competition, advertising rates stay firm or even go down. It is also contended that to the extent that shoppers continue to compete, it will be much easier for a new paid newspaper to enter the field. It is noted that the Association believes that interstate commerce regulations can apply to their problems. (MKM)
