Multi-level networks of regulatory authorities are considered as vectors of knowledge circulation, norm diffusion, and regulatory coordination. However, this is often assumed without empirical scrutiny of the concrete “micro-dynamics” between individual participants in networks, which remain a “black box” for analysts. This paper is mainly based on direct observation and informal interviews conducted during a meeting of the European Platform of Regulatory Authorities in charge of regulation of the broadcasting sector. It seeks to elucidate what deliberation, socialization, and learning, considered as devices typical of “soft” governance modes, mean as concrete social practices within a network.
