Introduction

Democratic primary candidate Bernie Sanders arrived in Seattle on August 8, 2015, to give a speech at a rally to promote his presidential campaign. Instead, the rally was interrupted—and eventually co-opted—by activists for Black Lives Matter (Figure 8.1).¹ Why did the group risk alienating Democratic voters by preventing Sanders from speaking? Because Black Lives Matter had been trying to raise awareness of the treatment of Black citizens in the United States, and the media has the power to elevate such issues.² While some questioned its tactics, the organization’s move underscores how important the media are to gaining recognition, and the lengths to which organizations are willing to go to get media attention.³

Freedom of the press and an independent media are important dimensions of a liberal society and a necessary part of a healthy democracy. “No government ought to be without censors,” said Thomas Jefferson, “and where the press is free, no one ever will.”⁴ What does it mean to have a free news media? What regulations limit what media can do? How do the media contribute to informing citizens and monitoring politicians and the government, and how do we measure their impact? This chapter explores these and other questions about the role of the media in the United States.
