Appointment-based TV –  (Time-and-channel-based TV, Linear Video, Linear Schedule, Linear Programming, Linear TV) – (1) Standard television service where the viewer watches a scheduled TV program at the particular time it’s offered, and on the particular channel it's offer on. Opposite of this would be incorporating the use of  DVRs, VCRs and/or Video on Demand. (2)When the broadcaster only wants your attention to be focused on the TV program. Typically this leaves little call for interactivity. They certainly don't want you to go to your computer and click on a related web site. They only want your attention to be on that show and it's advertisers. (3) Non-interactive television.

Appointment TV - Appointment TV, assumes that people will tune in at the same time every week, like clockwork, to watch their favorite shows. But the DVR and VOD  generation demands "anytime" TV. Video on Demand and Digital Video Recorders, easier and more efficient than VCRs, have made that a reality. See Appointment-based TV.

Linear to on-demand - (Linear-to-on-demand) - TV links for the viewer to activate to access on-demand content, often in the form of advertisements or merchandise for sale.
