Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for sharing digital media with a space. One of the methods includes receiving a request from a first user to provide digital media for presentation in a first physical space, the request identifying the digital media and a group of authorized users allowed to view the digital media. Sensors in the first space identify the authorized users located in the first physical space. That only authorized users can view the digital media is determined from the sensors. The digital media is provided for presentation in the first physical space while determining that only authorized users can view the digital media.
