For Abstractions, the most useful Associated Orgs are producers. The producers of a work do not change after the work has been produced, they do not vary by territory, they can usually be determined from the work’s included credits, etc. The original commissioning broadcaster can also be helpful in Abstractions. Other broadcasters, distributors, etc. are not useful for identification or deduplication of most Abstractions – and often cause more confusion than help. They become more important as you move down the registration tree to Edits, Clips, and Manifestations.
 An exception is Supplemental records (trailers, teasers, featurettes, etc.), which may be primarily identified by the distributor or broadcaster who commissioned them.
