'Because You Watched' Discovery Metric
Netflix is launching a new personalized row labeled 'Because you watched [title]' to improve content discovery. The team needs a single North Star metric for discovery quality AND explicit anti-gaming constraints to ensure the metric reflects genuine discovery rather than inflated engagement. The previous row iteration increased play starts but not watch-through — a red flag for metric inflation.
