Abstract: Internet-based enhanced radio. The radio appliance, through a network interface and Internet service provider, accesses a tuning service built upon a plurality of databases. The tuning service, databases, and related enhanced services provide the listener a variety of services, complimenting AM/FM radio broadcasts and Internet radio media stream broadcasts. The radio appliance user can request additional information concerning advertised products, identify and purchase soundtracks and CDs, purchase advertised products, and respond to market research polling and surveys. The tuning service and related enhanced services can monitor, collect, process, and store user music preferences, polling and survey results, user behavior statistics, and purchase and information requests. Market research and subscriber information is stored, retrieved, and updated in databases accessible to the tuning service.
