Speaking the language: acronyms and vocabulary that signal fluency

Knowing which bucket a company sits in tells you immediately what its main revenue lever is: subscriber growth (SVOD) or ad demand (AVOD/FAST).

The metrics everyone quotes

ARPU (Average Revenue Per User): total revenue divided by subscriber count over a period, usually monthly or annual. It's the single most-watched streaming metric because it shows pricing power, not just scale.

MAU / DAU (Monthly / Daily Active Users): how many people actually opened the app in a given window. Used heavily by ad-supported and social platforms (YouTube, TikTok) where "users" matters more than "subscribers."

Churn: the percentage of subscribers who cancel in a given period. A company can add millions of new subscribers and still shrink if churn is high. Low churn (roughly under 2 percent monthly is considered healthy for SVOD, as an industry rule of thumb) signals a "sticky" product.

CPM (Cost Per Mille/Thousand): what an advertiser pays per 1,000 ad impressionsimpressionsThe total number of times an ad or piece of content is displayed, regardless of clicks. Each display counts as one impression, even to the same person.Voir la définition complète →. This is the currency of the entire ad-supported ecosystem. Higher CPMs mean advertisers value that audience or that placement more (live sports commands premium CPMs; background FAST channels command lower ones).

CAC (Customer Acquisition Cost): what it costs, in marketing and promotional spend, to land one new subscriber.

Engagement (hours viewed): increasingly reported alongside subscriber counts because a subscriber who never opens the app is a churn risk. Netflix now publishes a biannual "What We Watched" engagement report, a rare bit of transparency in an industry that historically guarded viewing data closely. See Netflix's engagement report as a reference point.

Distribution and rights vocabulary

• Windowing: releasing content in sequence across channels (theatrical, then SVOD, then AVOD/FAST) to maximize revenue at each stage before it becomes "cheap" content.
• Output deal: a studio commits to licensing its content to one platform for a set period, common in pay-TV history and still used in streaming licensing.
• IP (Intellectual Property): the underlying rights to a franchise, character, or story, the asset that studios actually own and monetize across films, series, merchandise, and theme parks.
• Upfronts: the annual advance ad-sales marketplace (spring, historically broadcast-driven) where networks and streamers sell ad inventory months before content airs.
• Bundling: packaging multiple services together (Disney+, Hulu, ESPN+; or telecom-streaming bundles) to reduce churn by making cancellation feel like a bigger sacrifice.

Regulatory and structural terms

• MVPD (Multichannel Video Programming Distributor): the formal US term (used by the FCC, Federal Communications Commission) for a cable, satellite, or telco pay-TV provider, Comcast, Charter, DirecTV.
• vMVPD (virtual MVPD): an internet-delivered version of the same bundle, YouTube TV, Hulu + Live TV, FuboTV.
• Must-carry / retransmission consent: US rules governing whether cable operators must carry local broadcast stations and what they pay for the right (retransmission fees are a real line item on broadcaster income statements).
• AVMSD (Audiovisual Media Services Directive): the EU framework requiring streaming platforms operating in Europe to fund or carry a minimum quota of European content (commonly cited at 30 percent of catalogue), enforced at the national level by each member state's media regulator. This is the single most important piece of regulatory vocabulary for anyone discussing European streaming.

Market size, as of 2026 (estimates)

• US streaming video subscription revenue: commonly estimated in the $50 to 55 billion annual range, per industry trackers like Statista and analyst reports; treat exact figures as directional, not precise.
• US total video advertising market (linear TV + digital/streaming video ads combined): estimated in the $70 billion-plus range annually.
• Europe's SVOD market is smaller and more fragmented by language and national regulation, commonly estimated at roughly one-third to 40 percent of the US market size in subscription revenue, reflecting lower ARPU and more competitive local pricing.
• Global streaming subscriptions (all platforms, all regions) are commonly estimated in the 1.5 to 1.8 billion subscription range (note: this counts subscriptions, not unique households, since one household often holds several).

Flag all of the above as estimates: providers (Ampere Analysis, Antenna, MoffettNathanson, company 10-Ks) vary by 10 to 20 percent depending on methodology and what's included.

A worked calculation: ARPU and payback

Say a streaming service reports:

• 20 million subscribers
• $1.6 billion in quarterly streaming revenue
• $40 average CACCACCustomer Acquisition Cost (CAC) is the total sales and marketing spend divided by the number of new customers gained in a period. It measures how efficiently you grow.Voir la définition complète → per new subscriber

Step 1: Monthly ARPU

$1.6B revenue ÷ 20M subscribers = $80 per subscriber per quarter

$80 ÷ 3 months = $26.67 monthly ARPU

Step 2: Rough CAC payback period

It measures how efficiently you grow.Voir la définition complète → ÷ $26.67 monthly ARPU = 1.5 months to recoup acquisition costacquisition costCustomer Acquisition Cost (CAC) is the total sales and marketing spend divided by the number of new customers gained in a period.

This is the kind of napkin math analysts do live on earnings calls when a company gives revenue and subscriber counts but not ARPU directly.

Due diligence checks professionals actually run

1. Cross-check subscriber counts against churn commentary. A company touting subscriber adds while burying churn language in the footnotes is a yellow flag.

2. Separate ARPU trends from currency effects. Global streamers report revenue in USD; a strong dollar can make ARPU look flat or declining even when local-currency pricing rose.

Above 1.0, growth compounds on itself and becomes exponential.Voir la définition complète → or investor letter for "constant currency" language.

3. Check content amortization policy. Streaming companies capitalize content spend and amortize it over years; how aggressively they do this affects reported profitability.

4. Verify AVMSD compliance exposure for EU-facing platforms. A platform expanding into France or Germany has local content quota and contribution obligations that affect cost structure, not just optional local flavor.

5. Look at engagement, not just subscriber count. Hours viewed per subscriber (where disclosed) is a better churn predictor than raw subscriber totals.

Key Takeaways

• Master five acronyms first: SVOD, AVOD, FAST, ARPU, CPM. They cover 80 percent of what's said in any media earnings call.
• ARPU and churn together tell you more than subscriber counts alone; growing subscribers with rising churn is a warning sign, not a win.
• US streaming subscription revenue sits in the $50 to 55 billion range and Europe's is meaningfully smaller and more fragmented (estimates, 2026); always treat cited market sizes as directional.
• The AVMSD is the one regulatory acronym every Europe-facing media professional must know; it directly shapes content strategycontent strategyA strategy of creating and distributing valuable content to attract, engage and retain a defined target audience, rather than pitching products directly.Voir la définition complète → and cost structure.
