Is that kind of journalism imperiled by the transformation of the American news media? To put it another way, is independent news reporting a significant public good whose diminution requires urgent attention? Is it an essential component of public information that, as the Knight Commission on the Information Needs of Communities in a Democracy recently put it, “is as vital to the healthy functioning of communities as clean air, safe streets, good schools, and public health?”

Those questions are asked most often in connection with independent reporting’s role in helping to create an informed citizenry in a representative democracy. This is an essential purpose for reporting, along with interpretation, analysis and informed opinion, and advocacy. And news reporting also provides vital information for participation in society and in daily life.

Much of newspaper journalism in other democracies is still partisan, subsidized by or closely allied with political parties. That kind of journalism can also serve democracy. But in the plurality of the American media universe, advocacy journalism is not endangered—it is growing. The expression of publicly disseminated opinion is perhaps Americans’ most exercised First Amendment right, as anyone can see and hear every day on the Internet, cable television, or talk radio.

What is under threat is independent reporting that provides information, investigation, analysis, and community knowledge, particularly in the coverage of local affairs. Reporting the news means telling citizens what they would not otherwise know. “It’s so simple it sounds stupid at first, but when you think about it, it is our fundamental advantage,” says Tim McGuire, a former editor of the Minneapolis Star Tribune. “We’ve got to tell people stuff they don’t know.”

Reporting is not something to be taken for granted. Even late in the nineteenth century, when American news reporting was well established, European journalists looked askance, particularly at the suspicious practice of interviewing. One French critic lamented disdainfully that the “spirit of inquiry and espionage” in America might be seeping into French journalism.

Independent reporting not only reveals what government or private interests appear to be doing but also what lies behind their actions. This is the watchdog function of the press—reporting that holds government officials accountable to the legal and moral standards of public service and keeps business and professional leaders accountable to society’s expectations of integrity and fairness.

Reporting the news also undergirds democracy by explaining complicated events, issues, and processes in clear language. Since 1985, explanatory reporting has had its own Pulitzer Prize category, and explanation and analysis is now part of much news and investigative reporting. It requires the ability to explain a complex situation to a broad public. News reporting also draws audiences into their communities. In America, sympathetic exposes of “how the other half lives” go back to the late nineteenth century, but what we may call “community knowledge reporting” or “social empathy reporting” has proliferated in recent decades.

Everyone remembers how the emotionally engaging coverage by newspapers and television of the victims of Hurricane Katrina made more vivid and accessible issues of race, social and economic conditions, and the role of government in people’s lives. At its best, this kind of reporting shocks readers, as well as enhances curiosity, empathy, and understanding about life in our communities.

In the age of the Internet, everyone from individual citizens to political operatives can gather information, investigate the powerful, and provide analysis. Even if news organizations were to vanish en masse, information, investigation, analysis, and community knowledge would not disappear. But something else would be lost, and we would be reminded that there is a need not just for information, but for news judgment oriented to a public agenda and a general audience. We would be reminded that there is a need not just for news but for newsrooms. Something is gained when reporting, analysis, and investigation are pursued collaboratively by stable organizations that can facilitate regular reporting by experienced journalists, support them with money, logistics, and legal services, and present their work to a large public. Institutional authority or weight often guarantees that the work of newsrooms won’t easily be ignored.
