postmodern ads?

What is postmodernism? I have no idea. But I think, the work which you can't get information from or you can't figure out the connection within the elements it uses, can be postmodern work.

The mission of advertisements should be communicating information of the product, however, I find many advertisements quite confusing. I can't figure out what they want to say by adding this elements on the picture or by putting element A and element B together. Maybe I am out dated, which should not have happened. I am young and surrounded with so many information everyday.

So, I put those advertisements into the category of postmodernism, and come up with an explanation, or I should better call it supposal. In the development of advertising, people has tried information appeal and emotion appeal. However, consumers has get used to those appeals and aware of the expectation of those appeals. In other words, those approaches don't work in this days because of consumers' resisitence. As a result, advertisers try something new, something unexpected to catch people's eyes. They may don't have any reason or connection in a work, but presenting a feeling like cool or crasy, instead. What's important in these works is there "look".

Does it mean that in postmodern world, we don't need rationale, reason or direction. Feeling dominates everything, because seriously, I will fall in love with a brand just because the feeling it presents instead of anything else.
