Market Competition and Program Type Diversity: A Cross-Sectional Study of U.S. Television Stations

Using a cross sectional sample 231 randomly selected television stations, the study examines the relationship between market competition and station ownership structures and program diversity. The results from analyzing each station’s 2003 programming schedules for a constructed two-week period show that programs on television stations were concentrated in a handful of program types. Further, the Regression analysis showed that market competition (in terms of the number of television stations available in a market) has a negative relationship with program type diversity. We emphasize the preliminary nature of the results.
