PRETTY GOOD NEWS

David Brock, the founder of Media Matters, will head a new group dedicated not to correcting Noise Machine propaganda but to actively push back. From Ben Smith at The Poltico:

Brock said the group would be a ready-made vehicle to conduct media campaigns backing liberal causes on short notice, an analog to the partisan conservative message machine, giving liberals "the ability to create a real echo chamber."

He recalled that in 2004, his fledgling group had debunked "90 percent" of the content of an advertisement Swift Boat Veterans' for Truth that challenged Sen. John Kerry's war record — but had no way to distribute the information.

"Progressive Media USA will be a permanent part of progressive media infrastructure," he said.

But while the group's long-term goals may be broader, Brock says his commitment to the group is on a different timetable.

"I've committed to doing this through November," he said.
