Abstract

The present invention utilizes an aggregator for searching, packaging and delivering content. The aggregator processes requests, searches, provides search results and acquires content. The aggregator, operating in a communications network, includes a request and results processing server, a search engine server coupled to the request and results processing server and a content acquisition server coupled to the request and results processing server. A request and results processing server receives a request for content, the search engine server searches for the content and the content acquisition program acquires content for delivery to the user. The request and results processing server includes a search request processor that receives information related to a user'"'"'s search request and provides the information to a search results form builder that creates an electronic search request.
