With CNN taking a beating from critics for its often inaccurate and confusing reporting of the Boston marathon bombings last week, CNN President Jeff Zucker may have attempted to shore up morale by dispatching a memo to employees expressing is deep gratitude and admiration for their work. In front of the cameras and behind the scenes, you have shown the world what makes s CNN, he said in the memo, which was published in full by Politico.com. But Chicago Sun-Times TV columnist Lori Rackl may have got in the last word of censure on Sunday when she wrote that the major broadcast networks, which preempted most of their Friday-night programming to cover the latest developments in the unfolding story, produced mostly solid, comprehensive coverage that made the unraveling of rudderless CNN ... all the more apparent. She concluded: No network made it to the finish line without tipping over at least a few hurdles. But CNN showed us it needs to get in shape, fast. In Sunday's New York Times David Carr wrote that when big news breaks, we instinctively look to CNN. We want CNN to be good, to be worthy of its moment. That impulse took a beating last week. He added, It's clear after a busy week that Mr. Zucker can hire all the talent he wants, broaden the scope of their coverage and freshen the look of the joint, but if the network continues to whiff on the big stories, all of that will be for naught. But on CNN's own Reliable Sources, media critic Howard Kurtz appeared to try to put a lid on the matter by remarking that the cable news network owned up to the mistake, took responsibility. That, said Kurtz, was a good thing. And the mistakes did not seem to affect the news network's ratings, which rose 194 percent Monday through Thursday, according to Nielsen Research. And Rick Edmonds at the Poynter journalism school in Florida told Reuters that CNN's missteps were really important to those of us who cover the media. CNN still has a pretty strong reputation when it comes to the news.
