TV interfaces require entirely different UX patterns than mobile or desktop, but many teams lack specialized tools.
Build a framework or component library for TV-optimized navigation, input handling, and performance tuning. Target RDK, webOS, or Android TV.
Streaming platforms and TV manufacturers would pay to accelerate development. Agencies building TV apps are another buyer.
Start with an open-source core for basic navigation, then monetize advanced features or support.
The risk is competing with platform-native SDKs or big players like BrightScript.
