Concentration and Economics of Multiformity in the Communication Industries

Concentration within, and across 14 segments of the communication industries were assessed by analyzing data over a 5-year time frame. Within-industry concentration continues to increase across a number of segments in the communication industries. Economies of multiformity are introduced by the authors as a way to examine across-industry concentration. Data analysis indicates that across-industry concentration has not yet reached levels indicating high concentration, suggesting further expansion is possible by media conglomerates.
