This paper explores the effects of adding augmented reality (AR) artefacts to an existing TV programme. A prototype was implemented augmenting a popular nature documentary. Synchronised content was delivered over a Microsoft HoloLens and a TV. Our preliminary findings suggest that the addition of AR to an existing TV programme can result in creation of engaging experiences. However, presenting content outside the traditional TV window challenges traditional storytelling conventions and viewer expectations. Further research is required to understand the risks and opportunities presented when adding AR artefacts to TV.
