摘要

This paper provides a structural overview of the key media industries and deals primarily with the economic issues related to media concentration and crossownership. The economic markets that mass media firms participate in are quite complex and interrelated. The appropriate market definition depends crucially on the issue under consideration. Media products are highly differentiated by origin, by transmission technology, by packaging, and by an infinite variety of other attributes which may be relevant to characterization of a particular submarket. Few products are identical, yet most are, for some purposes, substitutes. Generalizations about the structure and concentration of the mass media are apt to be inappropriate under certain conditions. This paper describes some of the more interesting structural characteristics of firms in industries which can be considered to be part of the mass media.
