Pop culture is therefore part of an economic process which is likely to go on developing. Fashion is made instantly available to the widest possible market. It uses up visual ideas with alarming appetite. The hallmark of fashion is no longer elaboration, but novelty and impact. Pop culture involves a shift in attitudes towards the object.
