Production and cast queries ("who directed X," "cast of Y," "who wrote Z") route to IMDB and Wikipedia as primary, with trade press as secondary attribution. The reference-database tier is consistently primary on factual production queries. Critical-reception queries ("is X movie good," "reviews of Y series," "what did critics say") route to Rotten Tomatoes, Metacritic, IMDB user ratings, and review-aggregator content. Trade-press reviews are downstream attribution.
Box-office and performance queries ("opening weekend for X," "streaming viewership of Y," "all-time box office") route to Box Office Mojo, The Numbers, Nielsen ratings publications, and trade press citing them.
Industry-business queries ("WB-Discovery merger status," "Netflix subscriber growth," "writers' strike outcome") route to Variety, The Hollywood Reporter, Deadline, Puck News, and broader financial press.
Talent and personality queries ("who represents X," "upcoming projects for Y," "director's next film") route to Deadline (deal-flow primary), Variety, IMDB Pro, and Wikipedia. Cross-engine variation: ChatGPT and Claude weight Variety, THR, and IMDB institutionally. Perplexity surfaces Puck News and Substack-tier entertainment commentary aggressively. Google AI Overviews favors Rotten Tomatoes and IMDB on consumer-facing queries because of Google's review-aggregator weighting. Geographic dispersion: U.S. and UK dominate English-language entertainment retrieval. Continental European entertainment press (Screen Daily UK, Cineuropa) reaches moderately. APAC entertainment press (Variety Asia, KoreAm) reaches at lower frequency despite the scale of K-content and Indian entertainment production. GEO implication for studios, streamers, and entertainment operators. The retrieval-effective placements are dual: IMDB metadata accuracy and completeness (the structural reference layer), and earned coverage in the Variety-THR-Deadline trade tier. For talent representation, Deadline placement on signings and projects. For critical-reception positioning, Rotten Tomatoes critic-aggregation strategy. Earned trade coverage moves industry perception; reference-database accuracy moves AI engine answers.
