Even televisions are no longer sold as televisions. Instead, they are a component of a home-entertainment theater.
Linear multimedia combines video footage, sound, etc., but is without choices.
The easiest multimedia to produce, users react to, not with what they see. Cogent vignettes must be worked through and likely viewer choices mapped out logically before the presentation can be completed. Distribution media also is then limited to media that can be more dynamic. You must pay greater attention to the interface methodology used that will let the viewer control the experience. Videotape, for example, is a much more difficult medium for this type of presentation.
