My favorite media critic, NYU's Jay Rosen, is all done with CNN:
As of today, I have retired from criticism of CNN for falling short of some sort of journalistic standard that news providers should maintain. That activity no longer makes sense. Let someone else receive the “ratings, you idiot” replies on Twitter. I’m done. I’m pretty sure you don’t care about this announcement, either. Which nicely illustrates why I’m done.
Me? I wouldn't say I'm done with them -- but I share Jay's frustration. The catalyst for the conversation is CNN's heavily caffeinated coverage of the Zimmerman trial -- especially after so much other newsy stuff (plane crash, even deadlier train crash, and especially the coup/violence in Egypt) happened over the weekend. The second the gavel banged at 9 a.m. today, those stories fell down the memory hole. In fairness, the coverage on MSNBC and (I think) Fox News has been similar. But people had come to see CNN as a place where they could get international news when the others weren't up to the job. Those days have ended. The Zimmerman case is very important news, but tjis wall-to-wall coverage isn't really "news" but a kind of "entertainment" -- what Court TV was supposed to be for, before it became The March Madness Play-In Network.
