A system for managing delivery of content from multiple platforms maintains data for various video channels. Some of the video channels are television channels, while others are over-the-top (OTT) video content sources such as video streaming websites. The system includes a package generation module by which a service provider may define a package of both traditional and OTT channels to offer to subscribers in a unified programming interface. When a user uses the interface to select a set of video channels, the system compiles the set of the video channels in a subscriber package of both television and OTT channels. The system assigns a name to the subscriber package, and it stores the defined package and name, along with other information about the package, in a data storage facility for offering to a subscriber of content from the service provider.
