Journal ofAdvertising, Volume XX, Number 4 December 1991 We are pleased that our article entitled Advocacy Advertising and Boundaries of Commercial Speech (Cutler and Muehling 1989) has generated additional discussion and commentary on topic of advocacy advertising. As we pointed out in our original piece, the distinction between commercial and political speech, especially as it pertains to advocacy advertising, often is not clear (p. 40). Therefore, any attempt to further clarify matter should be welcomed, both from an academic as well as managerial/public policy perspective. As previously noted, advocacy advertising is a special form of advertising in which organizations express their opinions on (often controversial) issues in an attempt to sway public sentiment. Since a dominant element of such advertisements is a statement of opinion on an issue, advocacy ads have often been viewed as fully protected political speech and not subject to government (Federal Trade Commission) regulation and control. However, because advocacy ads also often contain some commercial element (e.g., paid sponsorship or reference to a product and its attributes), there is possibility that ads of this nature may be treated as commercial speech, and therefore subject to regulatory scrutiny. In our original paper, we provided a brief background and history of advocacy advertising and offered a number of reasons corporations may elect to use or eschew this ad form. In addition, we attempted to review significant legal cases and classification schemes that have been used to distinguish between commercial and political/editorial advocacy advertising. We also proposed some additional we felt may be helpful in making this distinction. Our proposal included consideration of a continuum that viewed likelihood of regulatory control in terms of ad's impact on ad sponsor, industry, business community, and society in general. As part of our discussion of continuum we noted that factors such as nature of ad's contents and context in which ad is placed, as well as other competitive/environmental factors, may be considered when making decisions regarding placement of advocacy ads along continuum. Also offered in article was a list of relevant questions/research topics others may wish to pursue in future. Middleton (1991) recently authored a comment on our 1989 article, suggesting that continuum we proposed helps little to distinguish between political and commercial advocacy advertising. At issue are two related points: 1) our article did not adopt, reject, nor suggest modifications to Supreme Court criteria (p. 78) and therefore is vague in its presentation of issues dealing with regulatory boundaries of advocacy advertising, and 2) our proposal would permit unconstitutional regulation of corporate political speech, thereby misclassifying political speech as commercial in nature. In this paper, we intend to address Middleton's comments and criticisms and place in perspective what we feel to be contribution of original article.
