Museology has been considered a multi-disciplinary field in today’s society. Museums as a recreational facility has become indispensable resource for the general public. Museums give people places to go, to learn and to enjoy themselves. Thus, management of a museum turns out to be a particular issue for public relations practitioners to keep a good relationship with key shareholders. This study aims to examine if and how museum management in Taiwan deals with the use of the Internet in recent decades to rise to fame and increase visibility. A content analysis of the top 10 most visited museums was employed. The researcher examined the museum’s web pages and fan pages on the social networking site, Facebook. The constructs that were measured were: Trust, Relationship Satisfaction, Relationship Commitment, and Exchange of Relationship. Results revealed that “Relationship Satisfaction” was found to be on all websites examined. All museums allow visitors to leave messages and provide simultaneous feedback on their websites so as to strengthen interaction with Internet audience. However, one-way communication was still seen on some museums’ WebPages and social networking sites. For both public and private museums in this study, there are still needs for improvement in communicating with target as well as potential publics when it comes to the fast growing online world.
