Arguably the most comprehensive examination of news media arrives in the form of the annual State of the Media report from the Pew Center's Project for Excellence in Journalism. It looks at each platform, trends in creation and consumption, some of the economic conditions and ambitions, and summarizes the environment in which journalism (primarily North American journalism) operates.

This year's report is out, and not surprisingly its focus is on the technological thrust of content delivery. Its findings note a rapid growth in mobile consumption. that social media are not yet large drivers of news, that television news continues to grow, that subscription models will expand, and that privacy considerations will increasingly intersect with newsgathering. It concludes that business models are still far from certain in this new environment and it chides the traditional media industry for not viewing the engineering function as an economic and operational necessity in the digital age.

As for standards, an area of the study's focus is on the reductions in local coverage of civic affairs. It notes that newspapers have been the primary sources of such information and that newsroom cuts have serious consequences for such coverage. The report also speculates that it may be a matter of time before the large technological platforms begin to acquire traditional content providers.

The report has several elements and is generally considered required reading in the industry.

It has been an interesting few days to view the combination of retraction, accusation and misinformation over stories in three American media outlets.

The most prominent involved This American Life and its January episode on the Foxconn plant in China that manufactures Apple products. The episode was based on a one-man theatrical production, but the program has lately discovered that elements of the show were more theatre than journalism.

There was a front-page column this week in the New Hampshire Eagle Times asserting that its rival, the Compass, had essentially plagiarized a sports column about a basketball game. The writer in question wasn't at the game, but liberally used material from the Eagle Times to appear to have been.

Then there was the matter of an obituary in The Oregonian of its editorial page editor. A "family friend" (actually, another editor in the newsroom) said police discovered the man in a parked car and rushed him to hospital. In fact, he died in the apartment of a woman with whom he'd been in a relationship for a year. The editor who was the source of the information was fired. She had misinformed the paper out of sympathy for the man's wife. The paper ran an extensive account of the matter later in the week, but did not note it fired the editor.

Two articles in recent days highlight the ethical challenges of Silicon Valley tech bloggers.

Many bloggers and their organizations separate their editorial efforts from any economic pressures involving advertisers or those they cover.

But in some instances bloggers are accepting investments in their operations and writing about those benefactors without much identifying or avoiding the conflicts involved.

In some instances bloggers are soliciting investments to create their own venture funds and writing for presumably large audiences about the companies they feature --- likely positively, and almost assuredly not before they parlay their insider knowledge into greater wealth.

The articles in the Los Angeles Times and on The Daily Beast acknowledge that blogging isn't necessarily journalism and that many bloggers are now the 21st century equivalent of the public relations firm.  But both are clear that there are conflicts galore in this new trend.

Arthur S. Brisbane, the public editor of The New York Times, writes this week about the value of using the news organization's website to reinforce its value with readers.

Brisbane notes how the web has deconstructed the traditional way in which content was organized, and in that new dynamic is a relationship that needs a new arrangement. He sees the website's organization as an important ingredient in that redefinition.

Among other things Brisbane says the site should have a clear place for an exchange with readers. He believes the Times newsroom and readers need this portal.

He also says the site needs an updated list of Times journalists and their areas of coverage. He notes the existing listings are not current.

The site also needs a searchable archive of ethics policies, a form to launch complaints and seek corrections, and (without a great deal of selfishness in the way he puts it) a clearer path to read the public editor's columns.

He adds: "Would a reader portal on NYTimes.com offset the centrifugal effects of the digital revolution? Certainly not. But as the model for publishing news changes rapidly, it is important to find ways to ensure that the center holds—and to fortify the core values that ultimately define how readers view The Times. The reader portal would be a concrete step in that direction."

In his latest The Media Equation column, The New York Times' David Carr notes the problem of the "burped up" thought that is Twitter, particularly when it intersects with professional expectations.

Carr cites the recent suspension of CNN's Roland Martin following a Tweet during last week's Super Bowl. Carr writes a thoughtful and self-deprecating look at the challenge of using social media when his employer has high standards. The instant judgment isn't always congruent with the overall judgment.

He concludes that 140 characters makes it difficult to be journalistic, even if it is fun and even if is a requirement.

The first phase of the Leveson inquiry into journalism conduct is drawing to an end, and the influential British media publication Press Gazette has created a new "manifesto" for journalists in light of what it has heard.

Its Journalists Code, designed to assist the deliberations of the inquiry, would require a signed pledge from journalists to uphold several provisions, including:

- More respect for the privacy of celebrities, but continued scrutiny of any illegality, dishonesty or hypocrisy.

-Greater transparency among news organization to deal with press inquiries about them.

-A ban on mentions of advertisers in editorial content.

-Libel reform to protect journalism in the public interest.

-A stronger Press Complaints Commission that can stipulate how corrections and rulings should be published.

-An independent commission with a majority of its non-journalist members.

-An end to unpaid internships.

-An end to copy approval by publicists and others pre-publication.

With a U.S. election looming, Twitter has created a new hub to train journalists on best practices to use the microblogging service.

The @TwitterforNews account shares, in 140 characters or less, tips for journalists. But the hub, Twitter for Newsrooms, is a more thorough guide to researching, reporting, engaging, networking and maintaining security.

"We want to make our tools easier to use so you can focus on your job: finding sources, verifying facts, publishing stories, promoting your work and yourself—and doing all of it faster and faster all the time," the service says on the site.

Arthur S. Brisbane caught some flak a week or so ago when he wrote about the need for fact-checking --- or as he called it, truth vigilantes --- at his news organization. Some inferred he meant the TImes needed to publish facts instead of fiction and thought it was an obvious sentiment.

But Brisbane was after something more, a form of regular challenging of assertions that often slip into stories without much thought. In some instances a countering view will "balance" that assertion. Brisbane believes that's a false balance. 

What he wants is a reality-check, or some sort of measured rebuttal, particularly as an election approaches in the United States. He agrees it can't be argumentative, but believes there is room to improve journalism standards by keeping a more vigilant watch on rhetoric.

His latest column lays out the case.
