This paper discusses the definition and characteristics of the art of digital media, introduces the application fields of digital media, and analyses the current situation faced by digital media art: the development of digital media art is facing the problem of rapid technological update and short life cycle; the knowledge and technology threshold of digital media art is high; the protection and inheritance of digital media art works have also attracted attention; the commercialization of digital media art is also an urgent problem. The commercialisation of art is also a problem that needs to be solved urgently. Finally, a series of countermeasures are proposed: the government and academic organisations should increase their support and investment in digital media art, and provide artists with a better creative environment and resources. Artists should strengthen their technical skills and interdisciplinary co-operation in order to adapt to new technologies and creative demands. Relevant departments should also strengthen copyright protection and market supervision to provide a good environment for the commercialisation of digital media art.
