This study is designed to examine comparative advertising as a viable advertising strategy in today's competitive business environment. Frequency and use of comparisons by the selected key industries and advertising agencies are investigated. Analysis is conducted to determine similarities and differences between firms who elect or avoid comparative advertising. Based on an analysis of the findings, certain conclusions are presented. The industry leader is not likely to use comparative advertising in most industries. Firms that are fourth or smaller in market share are most likely to use comparisons. However, the smallest firms, in terms of dollar sales volume, are least likely to use comparative advertising.
