Abstract: The network presentation system includes a database on a network server, the database being administered and controlled by an administration software module. The administration module creates individual images from text and/or visual material and then organizes a series of such images into a presentation which is stored in the database. The presentation is displayed on the screens of the individual PCs in the network by the action of a messenger software module present in each PC, following passage of a selected amount of time during which the PC is on but is not used. The messenger module maintains control over the presentation of the images in the particular presentation sequence following interruptions of actual use by the PC. A PC user has the capability of returning the PC to its conventional use, but also has the capability of controlling the presentation to an extent, or even changing to an entirely different presentation among the several which may be available to that specific user.
