Will the real world be replaced by the virtual world? Many theorists have already come up with critical prospects for its erosion and replacement, and now seems to be the time for such prospects to emerge. However, this article argues that the development of technology does not tend to expand the importance of the virtual world, but rather aims at various and complex connections between the real and the virtual. And it attempts to prove the validity of the argument through analysis of changes in Internetbased art. Net.Art showed characteristics such as virtuality, interactivity and technologyintensiveness by focusing on exploring the technical characteristics and possibilities of the Internet. On the other hand, Post-Internet Art has attempted to confirm the emergence of more diverse works, such as more indirectly revealing the impact of the Internet and re-emphasizing physical and tactile experiences. These characteristics can be defined as on-offline traverse and multi-platform dispersion.
