1. A machine-implemented browsing method, comprising: performing a context search based on information associated with at least one media object, wherein the performing of the context search comprises searching a first database of indexed references to web pages and other documents based on search criteria derived from information extracted from the at least one media object, wherein the performing of the context search further comprises generating a context search query from information associated with the at least one media object, transmitting the context search query to a first search engine operable to query the first database in response to receipt of the context search query, and receiving a first search response from the first search engine; performing a context-sensitive search based on results of the context search, wherein the performing of the context-sensitive search comprises searching a second database of indexed references to web pages and other documents based on search criteria derived from the results of the context search, wherein the performing of the context-sensitive search further comprises generating a context-sensitive search query from the first search response, transmitting the context-sensitive search query to a second search engine operable to query the second database in response to receipt of the context-sensitive search query, and receiving a second search response from the second search engine; and presenting information derived from results of the context-sensitive search.
