New Media Art reflects the dramatic creative and cultural shifts in science and technology of the past century. With these shifts, the multitude of forms of art-making have expanded to include a wide range of ideas and techniques. Following several decades of new contributions, this plurality of expression has resisted monolithic or curatorial approaches to organization along the lines of media. This paper defines knowledge cultures as flexible, overlapping, non-exclusive, ideological sub-groups and seeks to identify such groups within the practice and theory of New Media Art. While practising groups may be associated with specific media such as games, 3D printing, or artificial intelligence, we seek to identify knowledge groups by their explicit, hidden or shared ideological principles.
