This study adopted the theory of the niche to investigate the competitive relationship between three news media—Yahoo news, television news, and electronic newspapers. Two research methods, intensive interviews and a nationwide telephone survey, were employed to collect data for this study. The telephone survey resulted in 1002 valid telephone calls. This study found that Yahoo news did not produce its own news, but it was perceived by the respondents to be equivalent to television news and that the respondents perceived the strengths of Yahoo news and television news to be very different. Therefore, this study predicts that the two media would be able to coexist in Taiwan's news media market. Furthermore, the data from the niche analysis show that Yahoo news and television news were generalists, while electronic newspapers were specialists.
