Abstract
This study examined the programming of terrestrial and BS digital broadcasters by genre from the viewpoint of economics, using programming data for 8 weeks in 2010. The results showed that program genres with many broadcast hours are different between private broadcasters and a public broadcaster, NHK, and between terrestrial broadcasters and BS digital broadcasters. This study also found that broadcast hours by genre were evenly distributed among the 3 NHK BS digital channels, although each channel has been differentiated. Furthermore, except for TV Tokyo and BS Japan, there were few cases where programs in the same genre were provided at the same time by terrestrial and BS digital broadcasters under the same ownership.
