East Asian pop music idol production and the emergence of data fandom in China.

This article traces the formation of popular music idol industries in China and the emergence of data fandom. It charts the growth of digital platforms and historicizes the commercial and geopolitical itinerations linking cultural production in Japan, South Korea, and China. It locates data fandom as an integral part of the popular music industries reconfigured by digital social media platforms; a structural change from the production-to-consumption 'supply chain' model of the recording era towards emergent circuits of content that integrate industries and audiences. Data fans understand how their online activities are tracked, and adopt individual and collective strategies to influence metric and semantic information reported on digital platforms and social media. This article analyses how the practices of data fans impact upon charts, media and content traffic, illustrating how this activity benefits the idols they are following, and enhances a fan's sense of achievement and agency.
