Except for its military strength, a nation has taken popular products and cultures as another useful path to overcome other countries. Not only in domains of dramas or entertainment, Taiwan also has faced competitions in popular cultures and products from other countries with hardly any tiny bit of resistance, such as Hello Kitty, Japanese Idol Dramas and Korean Dramas. Compared to acceptance of alien cultures, Taiwanese ”local” cultures have went into difficult path in development. The study, therefore, would like to have direct discussion on issues of popular cultures, through documentary reading and analysis, then submit personal thesis. With discussion and analysis, as well as interpreting actual performances on popular cultures, on two individual cases, this study has made its conclusion and suggestion, and will be used as reference for those who are engaged in exploring ”local cultures”.
