Abstract. In this introduction to the special issue of Entertainment Computing on the new TV landscape, we introduce interactive television (iTV) research as one of the pillars in the field of entertainment computing. Although entertainment computing has been associated mainly with video-games, there is also more than a couple of decades’ research in computer applications for television. Contemporary infrastructures have been converging towards mature development platforms, but there are still several user experience issues in TV applications (TV Apps). Here, we explore significant contributions to interactive TV, and we provide directions for further research in user experience design for TV Apps.
