An exemplary computer-implemented television service system detects, while a media content processing device is presenting a user interface view associated with a television service within a display screen in communication with the media content processing device, an input command provided by a user of the media content processing device and representative of a request for customer support. In response, the system identifies a context within which the input command is provided by the user, selects, based on the identified context, customer support content provided by the television service and associated with the user interface view being presented within the display screen, and directs the media content processing device to present the customer support content within the user interface view. Corresponding systems and methods are also described.
