Abstract: A networked presentation system manages transmission of presentation units to the audience, and ensures that the presentation units are displayed to, or accessible by, the audience in the same sequence as the presenter intends. The networked presentation system includes a presenter system, a presentation server and at least one audience system that connect to each other using a data transmission network. The networked presentation system controls to deliver the active presentation unit to the audience systems such that whenever the presenter renders one presentation unit active, the networked presentation system makes the active presentation unit available to the audience system. The networked presentation system allows users of the audience system to configure the way the presentation units are displayed on the audience system, and to attach notes to the presentation units.
