Post-modernism developed as a concept in the mid-1980s and has received increased following over the years. As a concept, post-modernism defies definition because in this moment it means different things to different observers. (Guarino, Thomas, 2009).
“Postmodernism is hard to define, because it is a concept that appears in a wide variety of disciplines or areas of study, including art, architecture, music, film, literature, sociology, communications, fashion, and technology. It's hard to locate it temporally or historically, because it's not clear exactly when postmodernism begins.
“Perhaps the easiest way to start thinking about postmodernism is by thinking about modernism, the movement from which postmodernism seems to grow or emerge. Modernism has two facets, or two modes of definition, both of which are relevant to understanding postmodernism.
“The first facet or definition of modernism comes from the aesthetic movement broadly labeled "modernism." This movement is roughly coterminous with twentieth century Western ideas about art (though traces of it in emergent forms can be found in the nineteenth century as well). Modernism is the movement in visual arts, music, literature, and drama which rejected the old Victorian standards of how art should be made, consumed, and what it should mean.
