Three hundred years ago news travelled by word of mouth or letter, and circulated in taverns and coffee houses in the form of pamphlets, newsletters and broadsides." The coffee houses particularly are very commodious for a free conversation, and for reading at an easier rate all manner of printed news", noted one observer. Now, the news industry is returning to something closer to the coffee house. The Internet is making news more participatory, social, diverse and partisan, reviving the discursive ethos of the era before mass media. That will have profound effects on society and politics.
In principle, every liberal should celebrate this. A more participatory and social news environment, with a remarkable diversity and range of news sources, is a good thing.So what, many will say, if journalists have less stable careers? All the same, two areas of concern stand out.
The first worry is the loss of "accountability journalism", which holds the powerful to account. Shrinking revenues have reduced the amount and quality of investigative and local political reporting in the print press.
But old-style journalism was never quite as morally upstanding as journalists like to think. Indeed, the News of the World, a British newspaper which has been caught hacking into people's mobile phones, is a very traditional sort of scandal sheet. Meantime, the Internet is spawning new forms of accountability. A growing band of non-profit outfits such as ProPublica, the Sunlight Foundation and WikiLeaks are helping to fill the gap left by the decline of watchdog media.This is still a work in progress, but the degree of activity and experimentation provides cause for optimism.
The second concern has to do with partisanship.In the mass-media era local monopolies often had to be relatively impartial to maximise their appeal to readers and advertisers. In a more competitive world the money seems to be in creating an echo chamber for people's prejudices: thus Fox News, a conservative American cable-news channel, makes more profits than its less strident rivals, CNN and MSNBC, combined.
What is to be done? At a societal level, not much.The transformation of the news business is unstoppable, and attempts to reverse it are doomed to failure. But there are steps individuals can take to mitigate these worries. As producers of new journalism, they can be scrupulous with facts and transparent with their sources.As consumers, they can be catholic in their tastes and demanding in their standards. And although this transformation does raise concerns, this is much to celebrate in the noisy, diverse, vociferous, argumentative and stridently alive environment of the news business in the age of the Internet.The coffee house is back.Enjoy it.
