This paper investigates the relationship between market competition and program type diversity in the over-the-air television industry. Specifically, market competition is divided into intra-network competition and intra-media competition, i.e. terrestrial television vs. cable TV. Also this paper uses a comprehensive model of program types, with 281 program type categories, which have never been used in previous studies. The results show that program type diversity keeps decreasing over time and intra-network competition has a negative effect on program type diversity. Also, intra- network competition is a more important factor on program type diversity than inter- media competition.
