Past research documents the types of media Canadians use, but we know little about how media are assembled by audiences to interact with content. The goal of this research is to understand how audiences flow across diverse media in a single day. This 5-year series of studies focuses on how media users engage with and assemble different media throughout their day. We do not assume that audiences will use one medium at a time, instead, transmedia theory leads us to expect and account for media multitasking. To understand the contexts of transmedia practices, we are documenting not simply the number, type and time of media use, but also where people use media and for what reason they choose each medium. Our in-depth focus on a single day for each year’s diary is important, because it enables us to consider how media patterns map upon, mark and frame wider patterns of everyday life (breakfast, sleeping, lunch time, work, school, and leisure time).
