What is second screen behavior?

Second screen behavior is when viewers use a phone or tablet while watching TV or streaming. For Gen Z and Millennials, it’s now a natural extension of the viewing experience.

How common is second screen use among Gen Z and Millennials?

Very common. 85–89% of Gen Z use a mobile device while watching TV, and over 76% of Gen Z and Millennials say they often or always browse the internet on a second device. Smartphones are the dominant second screen, with ownership near universal.

What do people do on their second screens while watching?

Typical activities include checking social media and messages, looking up show-related info, and shopping links tied to what’s on screen.

Why does second screen behavior matter for streaming platforms?

It’s the norm, not the exception. Managed well, it drives deeper engagement, longer watch time, stronger retention, and new monetization opportunities.

How does Sound Dimension’s AiFi use the second screen?

AiFi turns phones into synchronized speakers, integrating them into the sound experience for social listening, surround sound across devices, and immersive group sessions.

How does AiFi improve engagement instead of causing distraction?

By keeping the phone inside the experience: the second screen becomes a sound extension of the story, reinforcing immersion rather than pulling viewers into competing apps.

Can second screen behavior help content go viral?

Yes. Second screens are where conversations happen. Shared listening and synchronized group moments are inherently social, boosting organic sharing and recommendations.

What monetization opportunities does AiFi unlock?

Premium synchronized live events, upsells for group sound experiences, sponsorships and branded events, plus audience intelligence on participation and session behavior.

How does AiFi help reduce churn?

AiFi makes the phone an extension of the platform, not an exit point. Synchronized sound across devices increases watch time, strengthens social bonds, and lowers churn.

Monetizing the Frame: Contextual Commerce for the FAST & AVOD Era

Let's talk

Streaming platforms know exactly what viewers are watching.

They just haven’t been able to monetize the exact moment.

Until now.

AiFi Scene Commerce is a synchronized commerce layer activated during connected viewing sessions.

Real-time, scene-triggered offers delivered to authenticated devices during synchronized viewing experiences.

What It Is

When phones connect as AiFi speakers, they become:

Verified, session-connected devices
Frame-accurate synchronized
Session-aware
Deterministically triggerable

This creates something streaming platforms do not currently have:

A synchronized, scene-timed, device-level activation channel.

A completely new monetization surface.

How it works

Layer 1, Session Intelligence

The platform knows in real time:

What content is playing
The exact timestamp
Who the host is
Number of connected devices
Geography
Subscription tier
Session duration

This is deterministic data, not probabilistic guessing.

Layer 2, Scene Trigger Engine

Offers can be triggered by:

Specific scene markers
Live sports moments
Product placements
Genre categories
Emotional peaks
Ad breaks
Sponsored “drop moments”

This enables precision activation tied to what viewers are experiencing together.

Layer 3, Device-Level Delivery

Tap-to-buy prompts
Limited-time drops
Coupon unlocks
Loyalty rewards
Companion content
Sponsored session bonuses

The TV stream is never interrupted.

The phone becomes the conversion surface.

The End of Guesswork

Today, streaming platforms spend millions on ads and brand partnerships with limited visibility into real conversion.

Linear ads are bought on reach.

Programmatic ads are bought on probabilities.

Brand integrations are bought on assumptions.

There is no deterministic link between what was watched and what was converted.

With AiFi Scene Commerce:

• Every device is authenticated
• Every activation is timestamped
• Every trigger is tied to a known scene
• Every interaction is trackable
• Every session has a defined host and participant count

This means:

You can measure:

Conversion rate per scene
Engagement per emotional moment
Revenue per session
ARPU uplift from activation
Advertiser ROI in real time

No guesswork.
No probabilistic attribution models.
No banner blindness.

For the first time, streaming ads become performance measurable at the moment level.

This is a new measurable revenue layer.

A New Revenue Line for Streaming Platforms

Today, monetization equals:

Subscriptions

Linear Ads
AVOD tiers

AiFi Scene Commerce adds:

Real-time commerce
Scene-based activation inventory
Performance-based brand deals
Sponsored group sessions
Limited-time drops
Premium interactive placements

Without increasing ad load.

Without interrupting viewing.

Without degrading user experience.

How It Works: From Patented Sync to Instant Sale

AiFi Scene Commerce is powered by our proprietary AiFi Synchronization Technology. Originally designed to turn multiple devices into a single, spatially-aware sound system, this same “handshake” now creates a deterministic bridge between the TV and the viewer’s phone.

The Deterministic Handshake

Unlike other “second screen” solutions that guess what a user is watching based on audio ACR (which is slow and battery-heavy), AiFi is already part of the session. When a phone connects to a TV or a “Leader” device to enhance the audio experience, it becomes an authenticated, frame-accurate node in that viewing session.

Sub-Millisecond Precision

Our patented AI audio engine manages latency with sub-millisecond accuracy. This means when a “Scene Trigger” occurs on the big screen—like a specific product appearing in an commercial, the commerce prompt arrives on the phone at the exact same micro-second.

The “Silent” Commerce Layer

Because the phone is already synced as part of the AiFi sound ecosystem:

Zero User Friction: No QR codes to scan and no apps to switch.
Deterministic Data: We know exactly who is watching, for how long, and which device is in their hand.
Non-Intrusive: The TV stream remains a pure, cinematic experience while the phone becomes the interactive “conversion surface.”

Beyond Audio: Visual Monetization

We have turned Sound into Infrastructure. By using the AiFi sync to lock the phone to the TV’s timeline, we allow streaming platforms to “Monetize the Frame,” delivering context-aware offers (like 20% Off or Limited Drops) triggered by the specific scene currently playing.

Stream smarter. Sound better.
