The reception of translated audiovisual contents in mobile devices has been largely ignored in Translation Studies. The current chapter is intended to identify key areas and challenges for research in Audiovisual Translation, so we can have a better understanding of how mobile contents are received and appreciated by users. Research in this field is modulated by the hybridity of audiovisual texts in mobile phones, since this type of text is multimodal, multichannel, and multiplatform. A second challenge is the potential target of mobile contents: the notion of audience(s) needs to be revisited in the new scenario, where ubiquity, immediacy, and global access to digital contents have sparked the diversification of users’ profiles. The spotlight of this chapter is on research opportunities within the reception of mobile contents; the complexity of investigating new types of global audiences clearly demands interdisciplinary approaches and research designs.
