Abstract
Systems and methods are described for using broadcast television systems as an implicit portal for solicitation of video on demand programs. A viewing device is monitored for the occurrence of a specific event, such as a channel change or the detection of a trigger mechanism programmed into a content program. When the event is detected, a user is prompted to notify the user of the availability of video on demand content related to the channel or program the user is watching. If the user indicates that he is interested in such content, available video on demand programs are presented to the user for selection. Means are also provided to prevent redundant and other unwanted prompts from appearing on the user's display.
