Abstract

Methods and apparatus for generating and delivering selected primary content and contextually-related, targeted secondary content to users of a network. In an exemplary embodiment, the network comprises a packet-switched data (e.g., IP) network such as the Internet, and the primary content comprises video or media clips that are user-selectable via a network site or web page. The primary content carries with it descriptive metadata that is accessed by a distribution server and forwarded to a secondary content source. The secondary content source (or its proxy) utilizes the metadata to identify and return contextually-related secondary content such as advertising links. This secondary content is then presented to the user in conjunction with the primary content, such as in a common display window and in a seamless fashion, thereby avoiding distractions to the user associated with generating ancillary windows or other display mechanisms, and providing the user with highly relevant secondary content choices.
