Televangelism is a specific media and religious phenomenon that arose in the middle of the 20th century in the United States of America as an innovative way of spreading the Christian message through television. From its early beginnings until today, this phenomenon has shown an incredible ability to adapt to various changes in the field of media technologies and success in overcoming various social and cultural challenges. The topic of this paper is focused on the study of the dynamic historical development of American religious television, with an emphasis on independent Christian broadcasters that began to dominate it since its beginnings in the 1950s, as well as the communication challenges and perspectives of this phenomenon. The aims of the paper are to show the key events on the radio that preceded the development of religious paid programs on television and to identify the factors that contributed to the dominance of televangelism. Furthermore, the paper will also present the main television preachers and their popular religious programs and explore how they have adapted their television services according to technological innovations from the mid-20th century to the present day. Also, the paper analyzes the ways in which television preachers attract the audience in order to obtain greater financial contributions for the development of their programs and will include the main criticisms directed towards this complex American media phenomenon. In conclusion, this paper will show how televangelism has adapted to the new age of digital technologies.
