【明報專訊】I recently saw an interesting film called The Greatest Movie Ever Sold, a documentary about the pervasiveness (滲透) of brand placement and advertising in modern society. Despite the film being kind of a satire (諷刺) on the phenomenon, it was ironically financed entirely by brand sponsorship. And despite the film's detailed analysis of how advertising in films and other media works to manipulate its viewers, I don't think people who have seen it will be any less affected by the ads around them.
