This article interrogates political brokerage on YouTube by examining the platform’s role in the construction of political discourses and in configuring the action of a new genre of political actors advancing a political agenda through historical revisionism. Using assemblage theory and drawing from technography, we propose the concept of “networked political brokerage” to characterize the mutually affirming relationship of YouTube’s governance mechanisms and alternative political influencers’ microcelebrity practices in building, complementing, and magnifying historical revisionist narratives through and within a network of algorithmically sanctioned videos. We illustrate how this interplay of platform logics and ‘cultures of use' privileges and legitimizes political content into knowledge without accountability. We argue for the importance of examining YouTube as a socio-technical driver of this political brokerage process in curating political information in this contemporary political scene.
