Postinternet denotes an idea in arts and criticism that refers to society and modes of interaction following the widespread adoption of the internet. The term emerged from discussions about Internet Art by Marisa Olson, Gene McHugh, and Artie Vierkant,. Guthrie Lonergan and Cory Arcangel have mentioned it as a term for being "internet aware", which some believe to be more accurate. Generally it is described as art that is about the internet's effects on aesthetics, culture and society.
Critics of the term claim that it falsely implies that there is a kind of art made after the internet has ceased to exist (and artists such as Rafael Rozendaal have criticized the ambiguity of "post-" in this instance).
The idea of art post internet was born in the wake of Internet Art, which gained significant traction in the early- to mid-2000s. Much like Internet Art, the postinternet art movement has roots in Dada, Fluxus, and exploration of net culture in general. Unlike Internet Art, postinternet art is less heavily influenced, at least in form, by telematic art, being more concerned in commenting on communications technology (the internet) than in being medium-native to the internet.
Works created within the postinternet paradigm often shares the aesthetics of the Internet Art, net.art and DataDada Art. It differs in that it does not use the internet only as a tool to produce art, but addresses the internet as a force that has altered social structures in both digital and physical spaces. Postinternet art is not necessarily art produced on the internet, but art that reflects the internet and the internet's effects on culture and society.
Postinternet art has gained some attention because of Petra Cortright's work, BRIDAL SHOWER and notably also Katja Novitskova's work, Post Internet Survival Guide. Postinternet art by Harm van den Dorpel has been covered on the Creators Project. In 2014, Shia LaBeouf took part in a collaborative art project that "was partly a response to how post-internet artists were using social media to promote their work and how that promotion became the work."
