The fourth edition of the essential introduction to digital art, one of contemporary art’s most exciting and dynamic forms of practice. Digital art, along with the technological developments of its medium, has rapidly evolved from the “digital revolution” into the social media era and then to the postdigital and post-Internet landscape. This new, expanded edition of Christiane Paul’s acclaimed book traces the emergence of artificial intelligence, augmented and mixed realities, and non-fungible tokens (NFTs) and surveys themes explored by digital artworks in the areas of activism, networks and telepresence, and ecological art andthe Anthropocene. It also examines issues surrounding the collection, presentation, and preservation of digital art. It looks at the impact of digital techniques and media on traditional forms of art, such as printing, painting, photography, and sculpture, as well as exploring the ways in which the Internet and software art, digital installation, and virtual reality have emerged as recognized artistic practices.
