This chapter describes the multiple roles of modern media in determining not only what consumers know, but also how and what they think. The exponential growth of ideologically driven cable channels and social media, dovetailing with cutbacks in newspaper staffing and coverage, point to the many ways that the power and reach of media are shifting even as they continue to reshape American society and norms. In this environment, multiple media compete for viewers, readers, and listeners who will click on their websites, buy their products, sign their petitions, and often accept their spin, especially if it reinforces personal perspectives. Thoughtful information about complex public health issues is easily lost in that context, leading too many people to base their decision-making on incomplete, biased, and even inaccurate information. For the news media to help build a Culture of Health, people need to understand how it works, what it does, and how it can be used for widespread benefit.
