Domestic digital signage industry has been growing in line with the Internet and intelligent devices like smart phones. However, policies for digital signage need to be supplemented because existing policies are only focused on regulations for outdoor advertisements. Moreover, while digital technologies have been developed, there are few contents technologies to support the digital technologies. In this context, this research aims to identify the problems in relation to the domestic digital signage industry and seek for measures to solve the problems. Various case studies and literature review were conducted to identify problems in terms of policy, technology and service, and measures for revitalizing the digital signage industry were suggested. The research is expected to help digital signage to serve as new convergence media available for customization targeting and user participation.
