Abstract
-
American democracy has been repeatedly buffeted by changes in media technology. In the 19th century, cheap newsprint and improved presses allowed
partisan newspapers to expand their reach dramatically. Many have argued
that the effectiveness of the press as a check on power was significantly compromised as a result (for example, Kaplan 2002). In the 20th century, as radio and then
television became dominant, observers worried that these new platforms would
reduce substantive policy debates to sound bites, privilege charismatic or “telegenic”
candidates over those who might have more ability to lead but are less polished, and
concentrate power in the hands of a few large corporations (Lang and Lang 2002;
Bagdikian 1983). In the early 2000s, the growth of online news prompted a new set
of concerns, among them that excess diversity of viewpoints would make it easier
for like-minded citizens to form “echo chambers” or “filter bubbles” where they
would be insulated from contrary perspectives (Sunstein 2001a, b, 2007; Pariser
2011). Most recently, the focus of concern has shifted to social media. Social media
platforms such as Facebook have a dramatically different structure than previous
media technologies. Content can be relayed among users with no significant third
party filtering, fact-checking, or editorial judgment. An individual user with no
track record or reputation can in some cases reach as many readers as Fox News,
CNN, or the New York Times.
