This paper focuses on live streams as interactional phenomena from an ethnomethodology and conversation analysis (EMCA) perspective. It discusses how streamers and viewers manage attention and engagement and how noticing-based actions constitute a powerful and crucial resource to produce and display these, finely tuned to the asymmetric communicative affordances of live streams, which, in the case of expository live streams, enact a streamer on display for the perceptual consumption of remote viewers. It discusses how streamers and viewers may produce noticing sequences and noticing-based sequences. It also discusses how the orientation towards noticing in expository live streams may become contagious and lead to a 'noticing effervescence.'
