Who really reports the news that most people get about their communities? What role do new media, blogs and specialty news sites now play?

How, in other words, does the modern news “ecosystem” of a large American city work? And if newspapers were to die—to the extent that we can infer from the current landscape—what would that imply for what citizens would know and not know about where they live?

The questions are becoming increasingly urgent. As the economic model that has subsidized professional journalism collapses, the number of people gathering news in traditional television, print and radio organizations is shrinking markedly. What, if anything, is taking up that slack?

The answers are a moving target; even trying to figure out how to answer them is a challenge. But a new study by the Pew Research Center’s Project for Excellence in Journalism, which takes a close look at the news ecosystem of one city suggests that while the news landscape has rapidly expanded, most of what the public learns is still overwhelmingly driven by traditional media—particularly newspapers.

The study, which examined all the outlets that produced local news in Baltimore, Md., for one week, surveyed their output and then did a closer examination of six major narratives during the week, finds that much of the “news” people receive contains no original reporting. Fully eight out of ten stories studied simply repeated or repackaged previously published information.” Source: Journalism.org
