# Streaming Monetization Models (AVOD vs SVOD)

## Prerequisite: Streaming Monetization Models (AVOD vs SVOD)

The source assumes the reader understands the basic tension in streaming platforms between **subscription revenue (SVOD)** and **advertising revenue (AVOD)**, and how platforms currently struggle to balance ad loads without triggering subscription cancellations.

- **SVOD** — Subscription Video on Demand: users pay a recurring fee; the platform's incentive is retention.
- **AVOD** — Advertising Video on Demand: ads subsidize a cheaper or free tier; the platform's incentive is ad load and monetization. Many platforms now run *hybrid* ad-supported tiers.

The conflict: aggressive ad loads (the [[concept-captive-audience-model]]) increase revenue per stream but drive annoyance, ad-blocking, and churn (see [[claim-captive-model-churn]]). This is the economic backdrop that makes the 'cost of a disengaged viewer' a real number and motivates the entire choice-architecture intervention.

**Why it's required:** Without this frame, the churn statistics and the platform-side rationale for granting ad control look arbitrary rather than commercially urgent.

**Enrichment note:** Formal economic models of streaming confirm that platforms switch between ad-supported and subscription models based on audience size, ad tolerance, and content costs, and that ads create user *disutility* — a genuine ad-revenue-vs-retention trade-off. Viewers tolerate ads that are low in intrusiveness and high in perceived value; mid-roll interruptive formats are least liked.
