Terry Heaton: TV News in a Postmodern World: New Metrics and Principles: What’s needed is a new metaphor to replace the old one, and new metrics upon which to place value in a world of unbundled media. The value will be there, because access to eyeballs (or eardrums) will always have value. But those eyeballs are scattered, knowledgeable, hip to our ways, and highly suspicious. This requires a completely counterintuitive set of metrics and principles.
Terry offers a long list here. I disagree that these are counterintuitive, however.
