Abstract
Systems and methods of determining viewership information are provided. A method of determining viewership information includes determining viewership information from multicast routing table data associated with one or more edge routers of a media content delivery service. Each edge router of the one or more edge routers is adapted to transmit media content streams to multiple devices via a first network. The method also includes sending data related to the viewership information to a requesting device via a second network.
