Abstract: Media, methods, and systems are disclosed for ad hoc, ambient, synchronous multimedia collaboration in a group-based communication system. Embodiments of the invention provide a way for users to quickly discover and initiate real-time collaboration sessions among groups of other users without the burden and overhead of a conventional call or video meeting. Users can quickly and easily discover and switch into and out of these synchronous multimedia collaboration sessions at any time, without disrupting the sessions for other participating users. This enables a diverse set of users to experience a rich multimedia collaboration session collaboration as a convenient ad hoc forum rather than a burdensome scheduled event.
