The comprehensive global information network broadcasting system and implementation thereof is designed to be used to provide a plurality of, what is commonly referred to as, Internet service providers with updated information through the use of high speed satellite links directly to the local Internet service provider from a centralized location. The satellite broadcasting system is combined with servers known as caching or proxy servers located at the client site which serve to store web and other data until the end user needs to access the data and a master cache center which coordinates the selection and transmission of information to those client sites via the satellite broadcasting system. The caching of data objects as close to the end user as possible will require less data to transit the backbones networks. The client site cache communicates to the master cache center via a connection to the Internet and the client site cache receives from the master cache center via the satellite broadcasting system and, in some cases, the Internet connection. Upon the receipt of a request from an Internet service provider, the information at the master cache will be transmitted from a ground station to a satellite and will be broadcast to all receiving Internet service providers using the broadcast system which overlays a capability onto the existing Internet that will allow real broadcast so that the data object can be transmitted once and received at all subscriber locations. Internet service providers will need to subscribe to the service to be able to receive these satellite transmissions, and in order to register their cache misses which is a way in which a subscriber indicates interest in a data item. A method of implementing this is disclosed using software for updating and optimizing of the local cache sites and capturing and processing the information through the receivers.
