This paper explores educational trade fairs as part of the contemporary networked governance of public sector education. The focus is on the forms and functions of network governance in educational trade fairs and how different powers of private and public networking actors and ideas are played out, including the wider implications for education. Based on an event ethnographic case study of a Nordic educational technology fair, the study identifies three significant forms of how network governance powers are constituted: through consensual culture, blurred public-private actor roles, and market individualised addresses. Together this network governance has de-politicising effects that mask power imbalances and evoke democratic challenges for public sector education. The paper discusses how diffused market networking powers shape a national public education sector, and the forms of resistance and responsibilities within such governance. The merits of in-depth process-based event ethnography, which includes social media data, are raised and problematised.
