Abstract:
Subscriptions to periodicals are arranged for via a communications network, such as the Internet, wireless or cellular links, satellites or a cable/DSL link, using a subscriber terminal. A selected periodical is downloaded via the Internet to the subscriber's terminal with the contents presented on a video display. An authorization code may be assigned to the subscriber terminal, the individual subscriber, or to both, with the code, or codes, verification by an authorizing authority prior to downloading of the requested subscription materials. The terminal is of the interactive type allowing the subscriber to select a specific periodical from a list of available periodicals, perform a word search covering one or more periodicals for a specific subject matter, change the subscription from one to another periodical on a daily, weekly, monthly, etc., basis, or even several times in one day on a real time basis. The subscriber pays a fee to the authorizing authority and receives credit units in accordance with the amount paid or the subscriber's account may be debited. These credit units may be used by the subscriber as desired until the units are used up. Each time a periodical is downloaded to the subscribe's terminal, the subscriber's account is debited. The authorizing authority maintains an account for each subscriber, periodically informing each subscriber of the number of credit units available as well as when the credit units are about to be used up.
