Abstract: Systems and methods enhance content from one source with content obtained from another source. Information about content, such as content that is or will be experienced by a user, is used to identify the content from another source. The content from the other source may be content of a different type than the content being enhanced. The content from the two (or more) sources are combined and provided simultaneously. The combined content may be provided using a set of one or more electronic devices.

Abstract: A method and system for mediated shopping. First, a client requests product information from a merchant or seller's web site through a mediator. Second, the mediator receives the requested information from the merchant, adapts the information into a format compatible with the client, and then provides the adapted information to the client. Third, the client sends the mediator requests to add or delete items from a shopping cart. In response to these requests, the mediator updates the shopping cart record. Fourth, the client sends the mediator a purchase request to purchase one or more items in the shopping cart. In response to the purchase request, the mediator updates the shopping cart record to reflect the purchase. The mediator also provided mediated payment services and delivery services so that customer information (e.g., credit card number and delivery address) is not revealed to the merchant.
