This paper examines the use of appropriation in contemporary internet art - postinternet art - in terms of internet technology and web content. The paper suggests that postinternet art reflects our cultural reality through the ubiquity and fluidity of internet services. This results to novel artistic practices that draw on the cultural connections made online by appropriating found web content and internet technology. The paper presents a study of 190 artworks from the ArtBase Rhizome’s digital archive between 2010-2015 to provide evidence on how and to what extent postinternet art appropriates the internet.
