Public media entities need to better work together to coordinate mapping efforts, writes Jessica Clark, director of the Center for Social Media’s Future of Media project, on MediaShift. One project she cited is the CPB-funded map being developed by the National Center for Media Engagement. The NCME is using Google Maps to layer common interests among funders, public media and communities. The New America Foundation also has started analyzing local media and government ecologies. And the University of Southern California’s Annenberg School of Communication is mapping ethnic media, “a crucial missing layer,” as Clark says. Now, if only all of them could cooperate: “Right now, communications researchers are still asking very different questions, and attending to different priorities. Developing common questions and data collection standards will require time, effort and focused collaboration.”
