Open online platforms, like YouTube, are a particularly popular medium for youth who are drawn to the low barrier for entry to reach a potentially global audience. Yet, much of the work that has been carried out focuses on identifying and filtering potentially inappropriate content and otherwise supporting children as consumers of media. This work seeks to understand and support youth as video creators. In this thesis, I will describe my foundational work investigating youth video creation on commercial platforms, present a novel exploration of design opportunities with a team of intergenerational youth and detail one specific design insight that blossomed from this exploration, the opportunity for collaboration in video creation.enThesis or Dissertation
