1. A method comprising:
receiving one or more broadcast streams comprising a first advertisement segment and a second advertisement segment;
obtaining a first fingerprint corresponding to the first advertisement segment, a second fingerprint corresponding to the second advertisement segment, and a third fingerprint corresponding to a third advertisement segment that is a master segment;
based on comparing the first fingerprint to the third fingerprint, making a first determination that the first advertisement segment non-identically matches the third advertisement segment within a threshold extent of similarity;
storing data indicating that the first advertisement segment is a first variation segment of the third advertisement segment;
based on comparing the second fingerprint to the third fingerprint and to the first fingerprint, making a second determination that the second advertisement segment non-identically matches the third advertisement segment within the threshold extent of similarity and making a third determination that the second advertisement segment does not identically match the first advertisement segment; and
storing data indicating that the second advertisement segment is a second variation segment of the third advertisement segment.
