Box-to-box Networking (Interactive TV) – (Might be known as Peer-to-peer) - When a brand or business’ product(s) can only communicate with users of that specific brand or business’ product(s). For instance peer-to-peer videocasting might be able to occur between, and among, only one company’s (for instance TiVo) subscribers and not between Tivo and Dish Network, Telewest or Sky Digital Video Recorder users.
