The health communications field has been rapidly changing over the past two decades. It has evolved from a one-dimensional reliance on public service announcements to a more sophisticated approach which draws from successful techniques used by commercial marketers, termed "social marketing." Rather than dictating the way that information is to be conveyed from the top-down, public health professionals are learning to listen to the needs and desires of the target audience themselves, and building the program from there. This focus on the "consumer" involves in-depth research and constant re-evaluation of every aspect of the program. In fact, research and evaluation together form the very cornerstone of the social marketing process.
