From nytimes.com:

Brian Williams of “NBC Nightly News” told PBS’s Charlie Rose on Tuesday that the shootings at Virginia Tech proved that viewers still wanted traditional network anchors.

Most don’t need more than one, however.

The excruciatingly close-up and continuous coverage of the massacre helps explain why viewers are increasingly turning to Charles Gibson of ABC. When it comes to an anchor’s presence at a major breaking story, less can be more.

And particularly in the middle of so wrenching a tragedy, tone matters as much as content. Hurricane Katrina, even more than 9/11, emboldened television newscasters to fold themselves and their feelings into the story, and that has led to the Anderson Cooperization of the evening news.

Network anchors often behave as if they are the nation’s grief counselors. One reason that Mr. Gibson has been gaining in the ratings could be that he acts like the nation’s newsman.

Mr. Williams and CBS’s Katie Couric were in Blacksburg, Va., on Monday, the day of the shootings — CBS that night extended the evening newscast to a full hour. Mr. Gibson, who didn’t arrive on the scene until Tuesday and delegated many interviews to ABC colleagues, was better than either of his rivals at keeping an even keel. His interview with a group of survivors on Tuesday night was more bearable to watch, mostly because his questions, posed in a kindly but neutral manner, solicited information, not emotion.

“And how would you describe his facial manner and demeanor?” Mr. Gibson asked, referring to the gunman. “Could you feel him pushing against the door?” Perhaps relieved to be asked for facts and not just their feelings, the students delivered both.
