This paper explores how Ghanaian mobile users interact with zero-rated mobile applications Free Basics and Wikipedia Zero. Based on semi-structured interviews with users and non-users of the applications, I discuss how mobile phone users perceive Free Basics and Wikipedia Zero, what motivates them to use or not use the applications, and how the availability of the applications influences their data-buying strategies. Findings suggest that respondents, including those who did not actively use the applications, understood and experienced Free Basics and Wikipedia Zero in ways divergent from the providers’ aim of expanding access to online content and services. *Mobile Video Dissemination for Community Health* Aditya Vashistha, Neha Kumar, Anil Mishra, Richard Anderson We examine the dissemination of mobile phone videos in the context of Projecting Health a community health project in rural India. Our research objective was to identify the most e ective means of promoting the distribution of health videos on a largely offine network of mobile phones in a resource-constrained environment. We compared three different distribution channels: mobile shop owners, laptop owners, and community health workers in a fourteen-week intervention that relied on data collected via missed calls from viewers and callbacks made to them. We present the design of our experiment, describe the challenges in deploying this experiment, and discuss overall ndings. All three distribution channels were successful in targeting the community; mobile shops had access to most community members but the community health workers were most successful in getting videos out to those who were most interested in viewing them. Many participants were motivated to distribute the videos for the bene t of community. However, the number of missed calls received decreased over time, suggesting the exploration of alternative mechanisms to extrinsically motivate intermediaries and viewers for broader video distribution.
