Conceptual art
Conceptual art at the end of the 20th Century spread to become a general tendency, a resonance within art practice that became nearly ubiquitous. Thus the widespread use of the term “post-conceptual” as a prefix to painting such as that of Gerhard Richter and photography such as that of Andreas Gursky.Benjamin Buchloh in "Art After Conceptual Art" points out that post-conceptual art is already emerging in the late 1970s and early 1980s in the photo-based appropriation art of Martha Rosler, Louise Lawler, Cindy Sherman, Peter Nagy, Barbara Kruger, Sherrie Levine and Dara Birnbaum.
