Postdigital is a term which came into use in the discourse of digital artistic practice at the start of the twenty-first century. This term points significantly to our rapidly changed and changing relationships with digital technologies and art forms. It points to an attitude that is more concerned with being human, than with being digital. If one examines the textual paradigm of consensus, one is faced with a choice: either the "postdigital" society has intrinsic meaning, or it is contextualised into a paradigm of consensus that includes art as a totality. Either way, Roy Ascott has clearly demonstrated that the distinction between the digital and the "postdigital" is part of the economy of reality.
Giorgio Agamben (2002) describes paradigms as things we think with, rather than things we think about. Like the computer age, the postdigital is also a paradigm, but as with post-humanism for example, an understanding of postdigital does not aim to describe a life after digital, but rather attempts to describe the present-day opportunity to explore the consequences of the digital and of the computer age. While the computer age has enhanced human capacity with inviting and uncanny prosthetics, the postdigital may provide a paradigm with which it is possible to examine and understand this enhancement.
In The Future of Art in a Postdigital Age Mel Alexenberg defines "postdigital art" as artworks that address the humanization of digital technologies through interplay between digital, biological, cultural, and spiritual systems, between cyberspace and real space, between embodied media and mixed reality in social and physical communication, between high tech and high touch experiences, between visual, haptic, auditory, and kinesthetic media experiences, between virtual and augmented reality, between roots and globalization, between autoethnography and community narrative, and between web-enabled peer-produced wikiart and artworks created with alternative media through participation, interaction, and collaboration in which the role of the artist is redefined.
In addition to the wide scope of artistic discourse, the notion of postdigital is emerging as a term that describes the exploration of our relationship to the computer age as a dominant paradigm in a time of global mixing, intertwined economies, population certainty and planetary limits, for example in the work of Berry (2014).
In 2018 a group of researchers has defined the postdigital in the context of science and education as follows: "The postdigital is hard to define; messy; unpredictable; digital and analog; technological and non-technological; biological and informational. The postdigital is both a rupture in our existing theories and their continuation. However, such messiness seems to be inherent to the contemporary human condition." The same group of researchers has also started the academic journal Postdigital Science and Education with Springer Nature.
Kim Cascone uses the term in his article The Aesthetics of Failure: "Post-digital" Tendencies in Contemporary Computer Music. He begins the article with a quotation from MIT Media Lab cyberpundit Nicholas Negroponte: "The digital revolution is over." Cascone goes on to describe what he sees as a 'post-digital' line of flight in the music also commonly known as glitch or microsound music, observing that 'with electronic commerce now a natural part of the business fabric of the Western world and Hollywood cranking out digital fluff by the gigabyte, the medium of digital technology holds less fascination for composers in and of itself.'
In Art after Technology Maurice Benayoun lists possible tracks for "postdigital" art considering that the digital flooding has altered the entire social, economical, artistic landscape and the artist posture will move in ways that try to escape the technological realm without being able to completely discard it. From lowtech to biotech and critical fusion - critical intrusion of fiction inside reality – new forms of art emerge from the digital era.
Jem Finer defined the term "post digital", in relation to his work, as "a return to a tactile relationship with ideas and materials informed by over 30 years of working with computers. A practice that seeks to transcend mediation via a screen and locate itself in the physical world, rather than at one stage removed, through digital representation". He first formulated the term in relation to his 1000-year-long musical composition," Longplayer". Though starting out its life as a computer generated piece of music, it needed to be "composed" in such a way that it could survive possible computer mortality, that it could assume any technological form.
Extending these ideas, in 2005 he proposed a "post-digital" sonic sculpture of indeterminate duration and composition, "Score for a Hole in the Ground" which was installed in Kings Wood, a forest in Kent in 2006. This bypasses the digital phase completely and uses only gravity, rain and wind as energy sources. Inspired by suikinkutsu, water chimes found in the temple gardens of Japan, Score for a Hole in the Ground uses tuned percussive instruments, played by falling water, to create music. A root like system of ducts collect and amplify the sounds, via a cor-ten steel horn, rising 20 feet above ground level. Finer describes his project as, ‘both music and an integrated part of the landscape and the forces that operate on it and in it’.
Florian Cramer explained the concept of postdigital art as an opposition to the hegemony of digital technology, in a parallel to the idea of post-colonial critiques of capitalism:
More pragmatically, the term ‘post-digital’ can be used to describe either a contemporary disenchantment with digital information systems and media gadgets or a period in which our fascination with these systems and gadgets has become historical. [...] Accordingly, ‘post-digital’ is arguably more than just a sloppy descriptor for a contemporary (and possibly nostalgic) cultural trend. [...] The simplest definition of ‘post-digital’ describes a media aesthetics which opposes such digital high-tech and high-fidelity cleanness. 
Postdigital art is new media art made art using glitches, circuit bending and databending. Other challenges involve the use of digital technology collaboratively, assuming their presence as part of the art world to manipulate. Artists such as Mark Lecky, Alice Anderson, Daniel Arsham and Jolan Van Der Viel have all produced work playing with a collaborative digital/physical relationship. Theo-Mass Lexileictous explores the role of digital distribution on art in the physical world.
