Multinational corporations carry out the strategy of "glocalization" to adapt their products for the local environment of the destination country. This strategy can be reflected in the intercultural advertising communication. In order to understand the intercultural advertising communication and its effectiveness, this paper analyzes the advertising appeals by three multinational corporations' advertising cases based on the theory of cultural values. The results show that the optimal sharing of cultural values of source culture and target culture is the key to the success of the glocalization strategy.
