Advertising as a field and industry often has a contentious relationship with both health communication and public health due to legitimate concerns about how advertising for certain products, such as alcohol and tobacco, could contribute to less-healthy decisions and behaviors. While acknowledging such concerns, advertisers and their approach to solving communication problems could also provide valuable lessons to those working in health communication. Indeed, advertising agencies are designed to develop creative and effective messages that change consumer behavior—and health communication practitioners and scholars aim to change population-level behavior as well. The perspective and approach of the account planner in the advertising agency—a role whose chief responsibility is to bring the consumer perspective into every step of the advertising development process and inspire effective and creative campaigns—would be particularly valuable to those working in health communication. It was account planning work that shifted traditional milk advertising from promoting it as a healthy drink to the iconic “got milk?” campaign, which positioned milk as a complement that makes other food better—an approach that drove positive sales after years of declining milk consumption. Yet many who work in health communication and public health often know little of how advertising agencies work or their internal processes that might be productively adopted. This lack of understanding can also lead to misperceptions of advertisers’ work and intentions. As an example, one might assume dense medical language in prescription drug advertising is intended to add unnecessary complexity to the advertisements and obscure side effects; instead, advertising professionals who work on prescription drug advertising have often been trained on clear communication—but cannot fully utilize that training because of regulations that require medically accurate terminology that might not be comprehensible to most viewers. Improved understanding of how advertisers can act as agents of change, and increased dialogue between the fields of advertising and health communication, could contribute to improved health communication research, practice, and policy.
