Casting’s Evolution: From Chromecast to Companion Apps — The Future of Second-Screen Control

Hook: Casting vanished from your phone — now what?

If you've ever opened a streaming app on your phone, tapped the familiar cast icon and watched your show jump to the TV, you know the relief of not juggling remotes and passwords. That convenience just got messy. In early 2026 Netflix quietly pulled broad support for mobile-to-TV casting, limiting it to a handful of legacy devices. For viewers, that raises a familiar pain point: where to stream and how to control what’s playing. For app makers and device OEMs, it forces a rethink of the role of the second-screen. This article traces the arc from the rise of casting to Netflix’s rollback, and lays out the practical, strategic moves that will define the next generation of companion apps and smart TV control.

“Casting is dead. Long live casting!” — Janko Roettgers, The Verge (Jan 16, 2026)

Executive summary — what's changed and why it matters

In January 2026, Netflix removed the ability to cast videos from its mobile apps to a broad range of smart TVs and streaming devices. Casting now works only on older Chromecast dongles (those without a remote), Google Nest Hub displays and a limited set of Vizio and Compal smart TVs (The Verge, Jan 2026). The practical fallout is immediate: users who relied on smartphone casting to avoid hunting for native TV apps now face friction, and device makers who leaned on casting as a simple integration path must accelerate deeper app-level partnerships.

But casting as a concept — letting one device hand off playback to another, or controlling TV playback from a phone — is not dead. It's evolving. The second-screen is shifting from a simple remote-replacement to a richer, contextual, multi-device experience: synchronized companion content, voice + AI interactions, live social features, and deeper smart-home integration.

The rise of casting: a quick history

Casting rose to prominence for three reasons: simplicity, interoperability and the explosion of mobile-first apps. Google’s Chromecast (2013) and later the broader Google Cast ecosystem gave developers an easy API to send playback to a TV without building a full TV app. Apple’s AirPlay offered a parallel path for iOS users. Standards like DIAL (the Netflix/YouTube discovery-and-launch protocol) and platform SDKs meant that a single smartphone app could reach a large number of living-room devices.

For content owners and app developers this was attractive: ship one mobile experience, support casting, and reach TVs without the engineering cost and certification cycles of native TV apps. For users it delivered frictionless handoff — and for device makers, casting made their hardware “smart” with minimal investment.

Why companies leaned on casting — a business view

• Lower engineering cost: One codebase on mobile, a standard protocol, and you reach TVs.
• Fast time to market: No need to go through multiple platform certifications and remote-control UX design.
• Convenience for consumers: Mobile-first sign-in, personalized accounts, and touch controls.

What changed in 2026: Netflix’s rollback and the signal it sends

Netflix’s move in early 2026 was a notable pivot. By removing broad mobile-to-TV casting support, Netflix made a clear statement: the company values tighter, app-level experiences on TVs over a lowest-common-denominator casting model. The change leaves casting only on select, often legacy, endpoints.

This rollback signals two strategic priorities: first, a desire for consistent feature parity and control on TV platforms (think downloads, profiles, interactive features); and second, a move to protect business models tied to device relationships, advertising features and data telemetry that are richer in native apps than in casted playback.

For developers and OEMs, the message is simple: relying on casting as an integration strategy is risky. Device-level partnerships, robust native apps on TV platforms, and rethinking second-screen roles are now urgent.

How casting still survives — and where it’s strongest

Although Netflix scaled back casting, several contexts keep the technique alive:

• Legacy devices: Older Chromecasts and some smart displays will still accept casts.
• Open platforms and web-first apps: Services that use web playback or WebRTC-based handoffs can still enable cross-device play.
• Non-premium use cases: Casual playback, user-to-user sharing, and guest scenarios where installing an app isn’t practical.

Trend signals from early 2026 — wider context

Two early-2026 developments highlight the shifting landscape. First, Netflix’s changes showed platform-first content distribution is back in focus. Second, the BBC’s reported negotiations to produce bespoke content for YouTube (Variety, Jan 16, 2026) shows broadcasters are experimenting with platform-specific delivery and companion formats — opportunities where a powerful second-screen can add value.

These moves reflect broader trends: content owners favor platform partnerships that surface exclusive features; device OEMs want differentiated UX to sell hardware; and users expect seamless, personalized multi-device experiences. That alignment pushes second-screen functionality beyond a simple playback control into an engagement layer that drives retention and monetization.

Next-gen second-screen features: what app makers and device OEMs will prioritize

Based on the marketplace signals of late 2025 and early 2026, here are the second-screen features most likely to see investment in 2026–2028.

1. Deep native TV + companion synergy

Expect two-way design: robust native TV apps plus companion apps that do more than act as remotes. Companion apps will surface synchronized behind-the-scenes content, character bios, multi-angle streams and interactive polls. The phone/tablet will be a contextual extension of playback rather than an alternative control scheme.

2. Low-latency sync via WebRTC and real-time protocols

For live events, watch parties and interactivity, latency kills the experience. App makers will adopt WebRTC and other real-time protocols to keep second-screen interactions in millisecond sync with the main screen. This trend also supports multi-room audio and live companion commentary.

3. AI-driven companion experiences

AI will create automatic scene guides, real-time translation/subtitles, character summaries, and context-aware recommendations that appear on the second-screen. Imagine pausing a show and getting an AI-generated timeline of the character’s backstory, or instant fact checks and historical context for documentaries — formats that map well to micro-documentaries and short-form companion content.

4. Privacy-first account linking & device auth

With casting rollback spotlighting the need for stronger TV apps, companies will invest in secure but frictionless device linking (QR codes, proximity auth, smart-home tokens) that preserve user privacy while avoiding repeated logins. At the same time, focus on discoverability and platform placement so users can find your native app quickly.

5. Cross-device handoff and continuity

Beyond starting playback, the future favors seamless handoff: move from phone to TV to car to AR glasses while keeping position, subtitles, and personalization intact. Standards and better state-sharing APIs will be key.

6. Social, synchronized viewing and creator tools

Second-screens will host chat, timed reactions, and creator overlays. Broadcasters like the BBC partnering with platforms such as YouTube create fertile ground for companion experiences tailored to platform behavior (clips, community posts, premieres). For teams implementing synchronized viewing, follow a live-stream SOP that supports cross-posting and real-time moderation.

7. Accessibility and mixed-modality controls

Companion apps will provide transcripts, alternative audio tracks, metadata-driven navigation for accessibility, and multi-modal controls (voice + touch + gesture) that make TVs part of the broader smart-home UX.

8. Monetization layers and micro-features

Premium companion features — synchronized director commentary, ad-free second-screen streams, or collectible interactive moments — will emerge as new revenue streams, especially for live sports and events. Consider integrations with live-stream shopping and commerce features to monetize companion interactions.

Practical, actionable advice — what to do now

Whether you build apps, make devices, or simply want a better viewing experience, you need practical steps today. Below are targeted recommendations.

For app makers (streaming services and broadcasters)

1. Prioritize native TV apps: Invest in platform-specific TV apps (Roku, Google TV, Tizen, webOS) — they’re the future of feature parity and telemetry. Work on platform discoverability early.
2. Design companions as extensions: Reimagine the phone/tablet as a contextual layer: synchronized metadata, interactive features, and accessibility tools, not just a remote.
3. Implement real-time sync: Adopt WebRTC or low-latency protocols for live and social features. Emphasize millisecond accuracy for watch parties.
4. Offer secure, simple auth: Use QR codes, temporary device tokens, and OAuth flows to reduce friction while protecting accounts.
5. Build for discoverability on platforms: Work with OEMs and platform stores to ensure quick access and promotional placement — who controls the home screen matters.

For device OEMs (smart TV and streaming box makers)

1. Differentiate UX: Offer unique second-screen capabilities (multi-view, dual-audio, companion app bridges) that justify hardware upgrades.
2. Open APIs carefully: Provide secure APIs for app-state handoff, metadata channels and low-latency signals while safeguarding user privacy.
3. Focus on performance: Optimize codecs and playback stacks (AV1, VVC where appropriate) to ensure smooth multi-device playback.
4. Partner with content owners: Move beyond passive hardware to co-developed experiences (exclusive features, pre-installed companions).

For viewers and power users

1. Update firmware and apps: When casting stops working, check for native TV apps or firmware updates that restore or replace functionality.
2. Use alternatives: If casting is gone, try AirPlay (for Apple users), HDMI dongles, or use the TV’s browser/web app for playback.
3. Check device compatibility: Verify whether your device is one of the supported legacy endpoints (older Chromecast, Nest Hub, certain Vizio/Compal models).
4. Secure your accounts: Keep two-factor auth on — shared devices and new linking flows increase attack surface.

Business implications and opportunities

Netflix’s decision is as much about data and control as it is about UX. Native TV apps allow richer telemetry on viewing behavior, which feeds personalization, ad targeting, and retention engineering. For broadcasters and creators, platform-specific companion content (like the BBC’s discussions with YouTube) opens sponsorship and discovery opportunities. Second-screen features that increase session time and social engagement will command investment. Creators should evaluate growth opportunities in this new model.

Predictions — what the landscape will look like by 2028

• Fewer reliance-on-casting scenarios: Casting will remain as a fallback but will no longer be the primary integration method for major services.
• Companions as retention engines: Rich, AI-driven second-screen features will be a key differentiator for streaming services competing for subscriber attention (see micro-documentary companion formats).
• Platforms own the home screen: Device makers that secure prominent placement for apps will capture a meaningful advantage in user engagement.
• Interoperability standards will improve: Expect consortiums and protocols to emerge that make cross-device state-sharing simpler and more secure.
• New hardware tie-ins: Smart glasses, in-car displays and mixed-reality headsets will become second-screen endpoints for select content.

Risks and friction points to watch

Several challenges could slow this evolution: fragmentation of TV platforms, privacy regulation limiting cross-device tracking, and the engineering cost of maintaining parity across endpoints. Additionally, consumer pushback against paid companion features or intrusive second-screen ads could force course corrections.

Real-world checklist: build, buy, or pivot — a short decision guide

1. If you’re a small streamer: Build a great mobile app, support a minimal native TV presence (web app), and offer a companion that adds value without heavy engineering — look for lightweight monetization tied to live commerce.
2. If you’re a large platform: Invest in native TV apps, buy or partner for specialized companion tech (real-time sync, AI metadata), and negotiate home-screen placement with OEMs.
3. If you’re an OEM: Build attractive APIs and SDKs, secure exclusive experiences with content partners, and advertise second-screen capabilities as a hardware differentiator.

Final take: casting isn’t dead — it’s being reborn

The 2026 shake-up around casting is less an obituary and more a pivot point. The era where mobile-to-TV casting served as a universal shortcut is ending. In its place comes a richer, more intentional second-screen strategy that blends native TV experiences with context-aware, AI-driven companion features. For viewers it means better experiences, if you have the right setup. For developers and device makers it means work: tighter partnerships, more nuanced product design, and a race to define the future of living-room engagement.

Actionable takeaways — what to do next

• Review your roadmap: replace reliance on casting with native TV and companion investments and study creator opportunity plays.
• Adopt real-time sync tech for live and social features (WebRTC/low-latency).
• Prioritize frictionless device linking and privacy-preserving telemetry; tune your directory/listing strategy via directory optimization.
• Explore platform partnerships and exclusive companion content (the BBC–YouTube model is a strong use case).
• For viewers: check device compatibility and consider native TV apps as the more future-proof option.
