“…The group of documents or subdomain focused primarily on the streamer employed well-established theories such as self-determination theory [ 53 , 54 ], affordance theory [ 10 ], normative theory of broadcast media [ 55 ], or grounded theory methodological analyses [ 6 , 56 , 57 , 58 ]. The second subdomain, focused on the receiver or the audience, was clearly underpinned by widely-tested theories: uses and gratifications theory [ 7 , 11 , 17 , 18 , 59 , 60 , 61 , 62 , 63 , 64 ], social identity theory [ 65 ], Lasswell formula [ 18 ], self-determination theory [ 18 , 62 , 66 ], theory of flow [ 18 ], compensation theory [ 67 ], social facilitation theory [ 62 ], social support theory [ 68 ], human information theory model [ 69 ], social identity theory [ 69 ], media richness theory [ 63 ], social cognitive theory of mass communication [ 70 ], and interaction ritual chains theory [ 33 ]. The third group, focused on the channel, relied less on well-established frameworks, mostly drawing on previous studies.…”
