Sponsored Content as an Epistemic Market Object: How Platformization of Brand-Creator Partnerships Disrupts...

Sponsored content allows brands to partner with creators to reach creators' audiences on digital platforms. However, both creators' and brands' incomplete understanding of this object generates two critical ambiguities: how to determine the value of sponsored content and how to effectively coproduce it. To better understand these ambiguities, the authors theorize sponsored content as an epistemic market object: an object that facilitates marketing functions but is only partially understood by the actors who use it. They analyze a dataset of interviews, podcasts, media articles, and third-party platform reviews about-and by-content creators, brands, and intermediaries. The findings show that brands, creators, and intermediaries create and apply knowledge to address valuation and coproduction ambiguities. However, this knowledge work is incomplete, creating asymmetries in value outcomes and power relationships in a brand-creator partnership. This research contributes to marketing literature and practice by highlighting the role of epistemic market objects in transformative market disruptions that alter the roles of, and the relationships between, market actors. The findings are transferable to other substantive areas such as generative artificial intelligence, the metaverse, nonfungible tokens, online news, and the sharing economy.
