Content from multiple different sources can be divided into segments based on time. Matched segments associated with each source can be identified by comparing content included in a first segment associated with a first source, to content included in a second segment associated with a second source. Syndicated content can be identified and tagged based, at least in part, on a relationship between sequences of matched segments on different stations. Various embodiments also include identifying main sequences associated with each source under consideration, removing some of the main sequences, and consolidating remaining main sequences based on various threshold criteria.
