Introduction
Electronic Program Guide (EPG) is a digital on-screen guide that provides users with schedules of current and upcoming TV programs. It is an essential feature for digital television platforms, enhancing the viewer’s experience by offering a convenient way to browse, discover, and plan their TV viewing.
Historical Context
The concept of EPG originated in the early 1980s with the rise of cable television, as it became necessary to manage a growing number of channels and programs. Early versions were simple text-based screens. With the advent of digital broadcasting in the 1990s, EPG evolved into a more interactive and sophisticated tool.

- Interactive EPG (i-EPG): Offers more features like search functions, program descriptions, trailers, and reminders.
- Cloud-based EPG: Stores data on remote servers, allowing for richer content and features, often integrated with smart TVs and streaming services.
Key Events

- 2000s: Integration of EPG with DVR and on-demand services.
- 2010s: The rise of cloud-based EPG and integration with smart home ecosystems.
Detailed Explanation
EPGs are typically presented as a grid displaying timeslots on one axis and channels on the other. Users can navigate through the grid to see what’s currently airing and upcoming programs. Advanced EPGs may include additional metadata such as program descriptions, cast information, and genres.
