From the perspective of virtual event participants, a backchannel is a (most often) public space for communication and annotation of the conversation, resource sharing, and a way of communicating without needing a working microphone or quiet space. Examples include Zoom Chat, Slack, and Twitter (using an event hashtag).

From the perspective of the event organizers, a backchannel is a private communication channel via which they can communicate about technical problems, scheduling changes, and other time-senstive issues.
