Art and kitsch defined as opposites
The word, kitsch, was popularized in the 1930s by the art theorists Theodor Adorno, Hermann Broch, and Clement Greenberg, who each sought to define avant-garde and kitsch as opposites. The art world of the time perceived the immense popularity of kitsch as a threat to culture. The arguments of all three theorists relied on an implicit definition of kitsch as a type of false consciousness, a Marxist term meaning a mindset present within the structures of capitalism that is misguided as to its own desires and wants. Marxists believe there to be a disjunction between the real state of affairs and the way that they phenomenally appear.
Adorno perceived this in terms of what he called the "culture industry", where the art is controlled and formulated by the needs of the market and given to a passive population which accepts it—what is marketed is art that is non-challenging and formally incoherent, but which serves its purpose of giving the audience leisure and something to watch or observe. It helps serve the oppression of the population of capitalism by distracting them from their social alienation. Contrarily for Adorno, art is supposed to be subjective, challenging, and oriented against the oppressiveness of the power structure. He claimed that kitsch is parody of catharsis and a parody of aesthetic experience.
Broch called kitsch "the evil within the value-system of art"—that is, if true art is "good", kitsch is "evil". While art was creative, Broch held that kitsch depended solely on plundering creative art by adopting formulas that seek to imitate it, limiting itself to conventions and demanding a totalitarianism of those recognizable conventions. Broch accuses kitsch of not participating in the development of art, having its focus directed at the past, as Greenberg speaks of its concern with previous cultures. To Broch, kitsch was not the same as bad art; it formed a system of its own. He argued that kitsch involved trying to achieve "beauty" instead of "truth" and that any attempt to make something beautiful would lead to kitsch. Consequently, he opposed the Renaissance to Protestantism.
Greenberg held similar views to Broch concerning the beauty and truth dichotomy, believing that the avant-garde style arose in order to defend aesthetic standards from the decline of taste involved in consumer society and that kitsch and art were opposites, which he outlined in his essay "Avant-Garde and Kitsch".
