The quantitative measurements of the essential properties and information communication abilities of physical media and media networks are proposed in this paper. Such as the number of sub-networks, the number of lecturing sessions, the number of accepted copies, information power factor and interaction ability et al. The measurement results for media networks of broadcasting, Client/Server, phone-like, single-producer peer-to-peer and multi-producer peer-to-peer types are derived respectively. They are the scientific foundation for understanding, analysis, comparison, monitoring, management, evaluation and utilization of media networks.
