Today, corporate communications which have been realized by the organizations have an important place in public relations discipline. Advances in communication and information technologies have a big impact on this relation. These technologies have also been bringing about the development of corporate web pages for organizations. It has been the primary concern of both private and public PR practitioners to keep pace with the speed of technological advances. As a communication medium, corporate web pages give a definite amount of support for public information, publicity and marketing communications activities since they are considered as window opening to the outer world. Besides, web pages give the possibility to direct activities of the corporation by getting response from the targeted audiences as they are a good way of gathering feedback. In the context of corporate communications, for public and private organizations, web pages have important functions especially in bridging the communication between the organization and its wide targeted audiences. Primary reasons for this can be increasing importance of new media, reaching information without time and space limits for the audiences and increased level of interactivity. In this paper, we are evaluating the degree of interactivity and governance on public and private organizations’ web pages for building a proper communication between audiences and the organizations. To assess this, we chose Turkey’s top 100 corporations in terms of net sales in 2005, both private and public which are listed by Istanbul Chamber of Industry (ISO) annually. These corporations are analyzed from interactivity and governance point of view.
