Many texts openly acknowledge that, given the diversity in today's audiences, they can have no preferred reading (check out your Reception Theory) and present a whole range of oppositional readings simultaneously. Many of the sophisticated visual puns used by advertising can be described as postmodern. Postmodern texts will employ a range of referential techniques such as bricolage, and will use images and ideas in a way that is entirely alien to their original function (eg using footage of Nazi war crimes in a pop video).
