The thesis examined whether there is a distinct boundary between art and advertising. The collected data showed how art and advertising are linked to each other and also differ from each other, in particular through the latter half of the 1900’s. What was happening in society came to have great impact on what happened in art and advertising. In postwar Germany, capitalism realism evolved from the German pop art where the art was removed from the art gallery and placed on the streets where the people were, in an era that was characterized by a gap between the rich and the poor. Capitalism Realism went on to advertising which at the time was using the techniques of subliminal persuasion and later turned into a post-modern advertising. The study included examples of artists who collaborate with advertising, where advertising has worked artistically and how the artist became a trademark. The study also showed that there are strong objections in the art world to working with advertising, but not vice versa. Advertising seems happy to work with arts.
