The quote struck me because it could just as easily be applied to radio spectrum - and it's a preoccupation of mine that spectrum is misleadingly characterized as a resource like land (see e.g. my post William James, consciousness, and the non-existence of spectrum)
The quote in context from the CSM:
Journalists are not professionals with a unique base of knowledge such as professors or electricians. Consequently, the primary economic value of journalism derives not from its own knowledge, but in distributing the knowledge of others. In this process three fundamental functions and related skills have historically created economic value: Accessing sources, determining significance of information, and conveying it effectively.
Accessing sources is crucial because information and knowledge do not exist as a natural resource that merely has to be harvested. It must be constructed by someone. The journalistic skill of identifying and reaching authorities or others who construct expertise traditionally gave journalists opportunities to report in ways that the general public could not.
Determining significance has been critical because journalists sort through an enormous amount of information to find the most significant and interesting items for consumers.
Effective presentation involves the ability to reduce information to its core to meet space and time requirements and presenting it in an interesting and attractive manner. These are built on linguistic and artistic skills and formatting techniques.
