And yet in 2009, Hollywood movie studios, radio and the Broadway theater, though smaller and much changed, are not dead. They learned to adapt and to collaborate with the monster.

In the Internet era, many sectors of American media have been re-enacting their at first complacent and finally panicked behavior of 60 years ago. Few in the entertainment business saw the digital cancer spreading through their old business models until well after file-sharing, via Napster, had started decimating the music industry. It’s not only journalism that is now struggling to plot a path to survival. But, with all due respect to show business, it’s only journalism that’s essential to a functioning democracy. And it’s not just because  as we keep being tediously reminded  Thomas Jefferson said so.

Yes, journalists have made tons of mistakes and always will. But without their enterprise, to take a few representative recent examples, we would not have known about the wretched conditions for our veterans at Walter Reed, the government’s warrantless wiretapping, the scams at Enron or steroids in baseball.

Such news gathering is not to be confused with opinion writing or bloviating  including that practiced here. Opinions can be stimulating and, for the audiences at Fox News and MSNBC, cathartic. We can spend hours surfing the posts of bloggers we like or despise, some of them gems, even as we might be moved to write our own blogs about local restaurants or the government documents we obsessively study online.

But opinions, however insightful or provocative and whether expressed online or in print or in prime time, are cheap. Reporting the news can be expensive. Some of it  monitoring the local school board, say  can and is being done by voluntary “citizen journalists” with time on their hands, integrity and a Web site. But we can’t have serious opinions about America’s role in combating the Taliban in Pakistan unless brave and knowledgeable correspondents (with security to protect them) tell us in real time what is actually going on there. We can’t know what is happening behind closed doors at corrupt, hard-to-penetrate institutions in Washington or Wall Street unless teams of reporters armed with the appropriate technical expertise and assiduously developed contacts are digging night and day. Those reporters have to eat and pay rent, whether they work for print, a TV network, a Web operation or some new bottom-up news organism we can’t yet imagine.

It’s immaterial whether we find the fruits of their labors on paper, a laptop screen, a BlackBerry, a Kindle or podcast. But someone  and certainly not the government, with all its conflicted interests  must pay for this content and make every effort to police its fairness and accuracy. If we lose the last major news-gathering operations still standing, there will be no news on Google News unless Google shells out to replace them. It won’t.
