The aim of this thesis is to provide insight into how YouTube audiences perceive the professionalization of vlog production styles and what happens to the parasocial relationship between viewer and vlogger, especially in relation to authenticity, in relation to this. This is done by a thematic analysis of comments on Valeria Lipovetsky’s YouTube video “We Need To Talk”, which serves as a case study. The analysis is done in background to theories of professionalization of influencers, parasocial relationships and authenticity. The results show that there is a tension between the perceived authenticity of the vlogger and the professionalization of vlog production style that is affecting the parasocial relationship between viewer and vlogger negatively. The distinguished themes point to vlogs filmed by a camera team being perceived to resemble reality television which is making the viewers feel disconnected with the vlogger. It is revealed that the audience prefers vlogs where the vlogger is holding the camera themselves, asthat is perceived as more personal and authentic.
