How come all Asian series, especially Taiwanese ones, have massive "promotion campaigns"whereas the American ones don't? You never hear about the cast for Grey's Anatomy setting up a promotions events in some mall in New York and signing autographys, whereas these things are quite common in Taiwan, Hong Kong, and Mainland (not sure about Japan or Korea but I woul assume so too). But it seems that this genre is mostly for the 'Idol' type series, because you never really see Chen Dao Ming or Tony Leung setting up these type of events.
