A new category of digital media has emerged in the living room: social TV. This relatively new concept can be defined as any application, website or software that allows viewers to interact with television programming and share that interaction with others. Currently social TV occurs in three ways: organically, as pure play or through TV- or set-top-enabled communication. This report will focus on the pure-play aspect of social TV as it relates to content providers, television networks and advertisers. It answers key questions relating to the segment’s growth potential, important companies, their competitors and likely business models for the future.
