Publisher content metadata was historically designed for editorial discovery – helping viewers find the right content, helping programming teams manage scheduling, helping editorial teams organize libraries. The genre labels, show descriptions, and talent metadata that help a viewer find a show do not tell a DSP what IAB category the content belongs to at level three, what emotional state the audience is in at the third commercial break, or how closely the content context aligns with an advertiser’s brand safety and emotional targeting requirements.
Manual IAB tagging at scale processes approximately 200 hours of content per week at level-one or level-two accuracy. That rate is entirely insufficient to keep pace with a major library’s ongoing content intake, let alone remediate the backlog of tens of thousands of hours of unclassified legacy content. The math does not work. The result is a metadata coverage problem that widens over time as new content enters the library faster than manual processes can classify it.
