The focus of the study is on production of media content, and it was conducted using a practical-theoretical approach. The practical part involves the making of MOJO! A mobile documentary about mobile journalism, filmed on two iPhones between 2018-2020. The theoretical thesis is a reflection on, and analysis of, the documentary process, in light of relevant media theory and research. By interviewing, observing and documenting the work of mobile journalists in different countries and contexts, this Master project hopes to contribute to a broader understanding of mobile journalism as a practice.
