When PowerPoint 2003 is launched — or when you create a new presentation — you typically see the first slide of the presentation. This slide is known as the Title slide — it contains placeholders for the slide title and the slide subtitle. Note that this layout is different from other slides which typically have a title placeholder with another placeholder for bulleted text (or a chart, graphic, etc.). All these other slides are influenced by the Slide Master, which governs their appearance and layout. The appearance and look of the Title Slide is influenced by the Title Master — this is a separate Master that is a subset of the Slide Master.
