In Dialectic of Enlightenment by Adorno and Max Horkheimer, the authors hold that the culture industry denies individualism by coercing people to be no more than consumers of mass art and entertainment. Largely, the culture industry is the entertainment business. This includes film, music, art, television, radio, and so on. The authors argue that products (entertainment and otherwise) are marked by sameness and similarity. The consumer believes he/she can choose from a wide variety, but this is an illusion. They also argue that the rise of the sound film is a prime example of the culture industry’s technique of pacifying and producing mindless consumers.
Those who are so absorbed by the world of the movie—by its images, gestures, and words—that they are unable to supply what really makes it a world, do not have to dwell on particular points of its mechanics during a screening.
They don’t think; they merely consume.
In Culture Industry Reconsidered, Adorno writes, "In a supposedly chaotic world, it [culture industry] provides human beings with something like standards for orientation, and that alone seems worthy of approval." A film is a mass produced commodity that offers the masses an escape from their working lives; or, a film can virtually copy the real world, thus celebrating it and making the consumer feel better about his/her life. In either case, a film-goer is pacified and given no motivation for critical thinking.
Popular films, music, art, and television tend to be very similar and very formulaic. They give the consumer a sense of familiarity and comfort. This practice induces conformity in the product (film) and the consumer, and because it induces conformity and passivity, the masses (consumers) never challenge the culture industry. They simply accept it. From the quote you cite above, the “order” that springs from the ideology of the culture industry is never challenged. This “order” is the whole business relationship between producers and consumers. It is a systemic order that reproduces itself and its consumers.
Film makers might claim to be making “art” or a product that is, even as an escape, something that improves peoples’ lives. One could argue that movies do serve a purpose in this way, but Adorno is rigorous here and claims that any industry that promotes conformity while discouraging critical thinking is necessarily bad for society because it discourages individualism.
