1.4 What Does Media Do for Us?

Media fulfills several basic roles in our society. One obvious role is entertainment. Media can act as a springboard for our imaginations, a source of fantasy, and an outlet for escapism. In the 19th century, Victorian readers disillusioned by the grimness of the Industrial Revolution found themselves drawn into fantastic worlds of fairies and other fictitious beings. In the first decade of the 21st century, American television viewers could peek in on a conflicted Texas high school football team in Friday Night Lights, the violence-plagued drug trade in Baltimore in The Wire, a 1960s-Manhattan ad agency in Mad Men, or the last surviving band of humans in a distant, miserable future in Battlestar Galactica. Through bringing us stories of all kinds, media has the power to take us away from ourselves.

Media can also provide information and education. Information can come in many forms, and it may sometimes be difficult to separate from entertainment. Today, newspapers and news-oriented television and radio programs make available stories from across the globe, allowing readers or viewers in London to access voices and videos from Baghdad, Tokyo, or Buenos Aires. Books and magazines provide a more in-depth look at a wide range of subjects. The free online encyclopedia Wikipedia has articles on topics from presidential nicknames to child prodigies to tongue twisters in various languages. The Massachusetts Institute of Technology (MIT) has posted free lecture notes, exams, and audio and video recordings of classes on its OpenCourseWare website, allowing anyone with an Internet connection access to world-class professors.

Another useful aspect of media is its ability to act as a public forum for the discussion of important issues. In newspapers or other periodicals, letters to the editor allow readers to respond to journalists or to voice their opinions on the issues of the day. These letters were an important part of U.S. newspapers even when the nation was a British colony, and they have served as a means of public discourse ever since. The Internet is a fundamentally democratic medium that allows everyone who can get online the ability to express their opinions through, for example, blogging or podcasting—though whether anyone will hear is another question.

Similarly, media can be used to monitor government, business, and other institutions. Upton Sinclair’s 1906 novel The Jungle exposed the miserable conditions in the turn-of-the-century meatpacking industry. In the early 1970s, Washington Post reporters Bob Woodward and Carl Bernstein uncovered evidence of the Watergate break-in and subsequent cover-up, which eventually led to the resignation of President Richard Nixon. But purveyors of mass media may be beholden to particular agendas because of political slant, advertising funds, or ideological bias, thus constraining their ability to act as a watchdog. The following are some of these agendas:

1. Entertaining and providing an outlet for the imagination
2. Educating and informing
3. Serving as a public forum for the discussion of important issues
4. Acting as a watchdog for government, business, and other institutions

It’s important to remember, though, that not all media are created equal. While some forms of mass communication are better suited to entertainment, others make more sense as a venue for spreading information. In terms of print media, books are durable and able to contain lots of information but are relatively slow and expensive to produce; in contrast, newspapers are comparatively cheaper and quicker to create, making them a better medium for the quick turnover of daily news. Television provides vastly more visual information than radio and is more dynamic than a static printed page; it can also be used to broadcast live events to a nationwide audience, as in the annual State of the Union address given by the U.S. president. However, it is also a one-way medium—that is, it allows for very little direct person-to-person communication. In contrast, the Internet encourages public discussion of issues and allows nearly everyone who wants a voice to have one. However, the Internet is also largely unmoderated. Users may have to wade through thousands of inane comments or misinformed amateur opinions to find quality information.

The 1960s media theorist Marshall McLuhan took these ideas one step further, famously coining the phrase “the medium is the message.^[1]” By this, McLuhan meant that every medium delivers information in a different way and that content is fundamentally shaped by the medium of transmission. For example, although television news has the advantage of offering video and live coverage, making a story come alive more vividly, it is also a faster-paced medium. That means more stories get covered in less depth. A story told on television will probably be flashier, less in-depth, and with less context than the same story covered in a monthly magazine; therefore, people who get the majority of their news from television may have a particular view of the world shaped not by the content of what they watch but by its medium. Or, as computer scientist Alan Kay put it, “Each medium has a special way of representing ideas that emphasize particular ways of thinking and de-emphasize others.^[2]” Kay was writing in 1994 when the Internet was just transitioning from an academic research network to an open public system.

A decade and a half later, with the Internet firmly ensconced in our daily lives, McLuhan’s intellectual descendants are the media analysts who claim that the Internet is making us better at associative thinking, or more democratic, or shallower. But McLuhan’s claims don’t leave much space for individual autonomy or resistance. In an essay about television’s effects on contemporary fiction, writer David Foster Wallace scoffed at the “reactionaries who regard TV as some malignancy visited on an innocent populace, sapping IQs and compromising SAT scores while we all sit there on ever fatter bottoms with little mesmerized spirals revolving in our eyes…. Treating television as evil is just as reductive and silly as treating it like a toaster with pictures.^[3]” Nonetheless, media messages and technologies affect us in countless ways, some of which probably won’t be sorted out until long in the future.

Marshall McLuhan’s theory of the tetrad is a framework for understanding the effects of media and technology on society. It’s a way to examine the impact of a medium by categorizing its effects into four distinct areas, forming a tetrad. These four aspects are:

1. Enhancement: What does the medium enhance or amplify? This looks at the positive attributes and what the technology extends or makes more efficient.
2. Obsolescence: What does the medium make obsolete or push aside? This considers what previous forms or technologies are replaced or diminished by the new medium.
3. Retrieval: What does the medium retrieve or bring back from the past? This explores what older forms or ideas are revived or recalled by the new technology.
4. Reversal: What does the medium reverse or flip into when pushed to its limits? This examines what happens when the technology is overextended, often leading to the opposite of the intended effect.
