Multimedia presentations help faster grasping of ideas and concepts than what simple oratory explanations can hope to achieve. As a result, multimedia-based teaching ensures lower costs for training sessions and improves the overall quality of such sessions. The greatest advantage of a multimedia presentation is that videos, audio, animation, and stills can all be used in a single window.  Concepts and patterns can be explained a lot easier using multimedia tools. E.g., statistical data when expressed as animated charts and graphs are more easily understood than when stated as mere numbers.

Answer:

Multimedia presentations challenge students to think creatively, thus, using images, video and animations alongside a text stimulates the brain. Student attention and retention increase.
