A term originally applied to the hanging or arranging of artwork for exhibition, its meaning has changed since the 1970s, primarily in the United States. Now the term also refers to site-specific artwork. Often this type of installation is composed of many items which create a message-bearing environment. Late 20th-century installation artists include Mathew Barney, Nayland Blake, Christian Boltanski, Walter De Maria, Chris Burden and Kiki Smith. Source: Robert Atkins, "Art Speak"
