Patent attributes
Various features are described for caching, tagging, and exchanging advertisements associated with network-accessible content. Advertisements may be retrieved and cached on mobile devices and other types of client devices prior to obtaining content containing references to advertisements. When content with an embedded reference to an advertisement is obtained, a previously retrieved advertisement can be loaded from the cache. Advertisements may also be tagged for later viewing. Users may revisit tagged advertisements at a future time, such as when wireless network connectivity is restored or when the user has more available time. Additional features facilitate bidding, by an advertisement server directly or indirectly associated with a client device, on advertising inventory associated with requested network content. In response to acceptance of the bid by a 3rd party advertising server, an advertisement from the associated advertisement server may be displayed.
