An application on Android TV devices responsible for displaying the user interface, managing installed applications, and providing a central point for navigation.

Historically, these have evolved from simple grid-based layouts to more sophisticated, content-driven interfaces that integrate recommendations and personalized experiences. This evolution addresses the need for streamlined navigation within the increasingly complex ecosystem of streaming services and applications.
