It is the aspect of hypertexture that makes digital content different from other traditional forms of content. Generally, hypertexture could be classified into the two following types: hypertext and hypermedia. The format of hypermedia content consists of different media, such as videos, images, voices, and words. This paper focuses on the relations between hypermedia and the newswriting of online news. This paper argues that hypermedia online news is similar to the so-called post-structuralism/deconstruction content, which recognized the impossibility of describing a complete or coherent signifying system since systems are always changing. However, the paper argues that because the news should present its content as clearly as possible, the hypermedia format in online news could bring the value of news into crisis since the meaning of hypermedia online news is often uncertain. How can this problem be resolved? Should we give up on the possibility of writing news within the format of hypermedia? In this paper, Bakhtin's theory of dialogism is introduced as a way to solve this problem. It was Julia Kristeva who used Bakhtin's theory of dialogism as an example to establish the importance of intertextuality in the realm of literary theory. However, this paper contends that the concept of intertextuality inherent in Bakhtin's dialogism is diffident to that of Kristeva. The function of intertextuality in Bakhtin's dialogism could bring the intertextual content into recognized meaning by the audience. From this perspective, the format of hypermedia could be applied to the writing of multimedia news.
