First-order effects

• Streaming services gain a larger addressable base, but the marginal new subscriber is increasingly a household already paying for two other services — growth now comes from stacking, not conversion.
• Nearly half of consumers report subscription fatigue, meaning services are acquiring users who arrive pre-disposed to cancel.

Second-order effects

• Churn becomes the central battleground: a late-2019 survey found half of users planning to add an OTT service while 64% of those intended to downgrade or cancel an existing one the swap-not-add behavior, forcing services to compete for rotation slots rather than permanent shelf space.
• Pricing pressure follows — with fatigue at 47%, services that raise prices risk pushing stacked households over their monthly tolerance, accelerating the trading-down dynamic.

Third-order effects

• If the pattern holds, the industry restructures around churn as a feature rather than a failure: by 2024 Antenna measured roughly a quarter of US streaming subscribers — 29M+ people — canceling three or more services in two years Antenna's serial-cancellation data, pointing toward a market of rotating subscribers, resurfaced catalogs, and bundle offers designed to lock in share.
• Aggregation shifts toward whoever controls the billing relationship — platforms that can package multiple services into one charge are positioned to capture the fatigued household.
