There are many differences between new media and traditional media,some of them may be seen as "cultural" barriers.As the monopolist in mass communication area,traditional media form a closed system,which leads to a self-centered culture.To maintain its authority and position,traditional media focus on the integration of all kinds of social groups rather than the satisfaction of individuals.However,new media are an open,decentralized and fault-tolerant system,with the combination of different cultures.They pay more attention to the individuals' needs and depend more on the participation and sharing of users.The cultural barrier is a main obstacle in the digitalization of old media and media convergence, especially in the convergence of Internet and television. <<
