Abstract: This study focuses on technology-mediated communication network used by journalists to gather news. In the Actor-Network Theory, technology is given the role as non-human actors forming the network. Roles are taken into account, like that of the human actors. The process by which an actor joins the network is seen as a translation, a process of assembling human actors and non-human actors. Translation assigns the role of each actor, it may fail or succeed. The success of translation is characterized by a network that is stable and lasting. This qualitative research with case study of the network of journalist community mailing list is to find out how journalists construct a network as well as the reasons for assembling and maintaining relationships. The study then found out not only about the actor network, but also the actor-sharing network and a network that can not be dissolved, or irreversible.
