A system is described for linking traditional media works, such as print and broadcast media for example, to a more interactive media conduit, such as the Internet. The system avoids the need to modify the media work in anyway. Instead, it employs a passive recognition system that uniquely identifies the specific work, such as a particular television or radio broadcast or printed commercial. The identification may be based in intra-work and/or extra-work information. Several different embodiments/environments are described. The best embodiment may depend, at least in part, on costs of hardware and communication. These costs can change over time. In one embodiment, all of the databases and computation are performed at the user's premises. In another embodiment, all of the databases and computation occur at remote sites that user premise equipment can query using uniquely identifying extra-work information, such as the time, place and station on which the work was broadcast. This second embodiment is most suitable for content that is published, e.g. magazines, newspapers, etc., or broadcasted, e.g. cable, satellite and terrestrial television and radio. Alternative embodiments, in which various operations are performed at both the user's premises and remote locations are also possible.
