Why Series-First Netflix Subscribers Churn, and How to Keep Them

You are a product manager at Netflix. Members whose activation came through watching a series show low retention. Why might that be, and what would you do about it? ```hint Trace the journey Follow someone who joined for one show: what they watch first, what the app offers them afterwards, and the point at which they are most likely to decide whether to keep paying. ``` ### Clarifying Questions - How is "activated by a series" defined: the first title watched was a series, or most viewing in the first weeks went to a single series? - Is retention low compared with members activated by films, or compared with the overall base, and at which point is it measured, such as the first renewal? - Is the effect concentrated among people who joined around one big new release, or does it also hold for long-running catalog series? ### What a Strong Answer Covers - Pinning down the cohort, the comparison group and the retention measure, and checking that the gap is not explained by who signs up or when - Hypotheses rooted in how series viewing differs from film viewing, each paired with the data that would confirm it - Solutions mapped to confirmed causes, spanning recommendations, release strategy and subscription options, and prioritized - Success metrics, an experiment plan and guardrails for the proposed changes ### Follow-up Questions - Releasing episodes weekly instead of all at once could stretch a subscription across more billing cycles. How would you test it, and what could go wrong? - How would you tell whether these members would have left no matter what, because they only ever wanted one show? - If many of them come back months later for the next season, should their churn still count as a problem?
