From a Washington Post article this morning:
The Project for Excellence in Journalism examined 53 outlets that regularly cover Baltimore over the course of one week last July. In looking at six major news stories, the group found that 83 percent of them — in print, television, radio, blogs and Web sites — were essentially repetitive. “Much of the ‘news’ people receive contains no original reporting,” the study says. “Fully eight out of 10 stories studied simply repeated or repackaged previously published information.”
Among the remaining stories that advanced the ball, 61 percent came from newspapers — from the Baltimore Sun to specialty publications — followed by 28 percent from local TV stations and 7 percent from radio. Twitter and local Web sites “played only a limited role: mainly an alert system and a way to disseminate stories from other places.”
The full study from the Pew Research Center’s Project for Excellence in Journalism is quite an interesting read as well (and yes, I recognize the irony of posting this to a blog).
