Due to the importance that the Internet has gained as a means of communication, literature on political communication has incorporated it as one of its preferred topics of focus. Literature stems almost entirely from Europe and the United States. Very little is known about the political use of new information and communication technologies (NICTs) in other parts of the world. The present chapter aims to provide evidence in that line, starting from the study of the incorporation of the Chilean political parties to the Internet. In specific, the following questions are answered: In what extent do factors such as the organizational characteristics of the political parties explain their greater or lesser adoption of NICTs? What do parties use NICTs for? Furthermore, although briefly, the authors will try to answer the question whether the parties have experienced change in their interaction with the citizenry and their bases because of the usage of NICTs. © 2010, IGI Global.
