The purpose of this study is to explore how broadcast news interviewers design news interviews by making use of news texts. Different from majority of intertextual researches using text analysis, this study adopts in-depth interviews with ten senior news interviewers to analyze how the intertextual news texts are chosen and constrained. This study finds that news interviewers define the interview through the genre intertextual relation between broadcast news interviews and news reports, and the intertextual practices are under the consideration of time, interviewees, and media characteristics. Moreover, the intertextuality of broadcast news interviews is constrained by the imagination of audience, the competition from other news media, and interviewees.
