  • Patent number: 6493722
    Abstract: A system, a method and a computer readable medium for distributing messages from a third-party to a group of subscribers by using subscriber information and subscriber preferences stored in a database so that the group of subscribers can form a community to negotiate a group purchase of a good and/or service from the third party. A subscriber selection system is used for querying the database using one or more subscriber criteria to form a group of one or more subscribers. The one or more subscriber criteria used to query the database is chosen by the third party, which allows the subscriber selection system to form a group of subscribers who satisfy the criteria for a type of subscriber that the third-party wants to send a message, such as an advertisement, to. A billing system, which is coupled to the database receives one or more messages from a third-party and then provides the one or more messages from the third party to the group of subscribers that was formed by the corresponding query of the database.
