The present invention includes a method of selectively delivering programming to a viewer station (e.g., a home) on an interactive television or televideo (IT) system. The method includes delivering a message to a selected viewer station having a selected video display set. The message may be delivered while the selected viewer station receives virtually any programming over the interactive televideo system, including selected programming that is chosen by a viewer at the selected viewer station and is carried on a selected programming channel. With reference to a preferred embodiment, the IT system transmits a message signal to the selected viewer station on a communication channel different from the channels carrying the programming, including the selected programming channel. The interactive station controller receives the message signal and generates from it a viewer message.
