The article concerns selected problems in the development of the Internet in terms of its impact on the religious attitudes of young Poles. On the base of the research on the use of the Internet and the development of religiosity, their situation is presented in the context of the situation of American teenagers. Americans are one of the largest media markets and have strong and traditional Christian communities. Therefore, certain trends in religious attitudes could have appeared earlier and outlined more strongly there than in other parts of the world. Which of them are reflected in the Polish situation? How is the Internet used by young users in the United States and Poland? Is there anything specific to the Polish situation in shaping religious attitudes via the Internet? The final results of the comparative analysis undertaken are to lead to conclusions showing the characteristics of the Internet that enable it to influence the shaping of the world-view and to forecast directions in which these changes may go. Research on the Internet’s influence on religiosity has a short history, but dynamic changes in both religiosity and technology call for the opening of new research spaces.
