Thesis advisor: Celeste Wells / This study examined the influence of a popular Youtuber in creating social discourse surrounding concepts of health, fitness, and beauty, employing a case study approach of the popular Youtube channel, Blogilates. Both visual and rhetorical analyses were conducted on the titles and thumbnail images of the top 50 most viewed Blogilates videos, and 10 videos were studied in depth. The findings established the concept of a unique power relationship between Youtubers and their viewers, which also explains the marked dissonance between the discourse posited by the channel’s marketing and the discourse posited in the actual video content. / Thesis (BA) — Boston College, 2017. / Submitted to: Boston College.
