The advantages of PowerPoint presentations include helping the audience focus on the message, creating a collaborative environment, and being able to easily share the presentation and information with individuals who were unable to attend the original presentation. PowerPoint presentations can also help ease the speaker's anxiety by focusing the audience's attention on the slides, text and images.
Utilizing engaging audio and video in a PowerPoint presentation can help keep the audience interested in the material. Video and audio also help the presenter better interact with the audience and deliver an "off the cuff" presentation that's less scripted and rigid. It's best that the presentation contain the right balance of audio, video and verbal material to ensure the main message is not diluted.
PowerPoint presentations can also help support teamwork in an office setting. Such presentations allow different team members to leave comments on individual slides and screens for others to view. Such comments can help clear up any confusion concerning material created by various team members.
PowerPoint presentations can be shared worldwide and uploaded to various websites, where they can be viewed by the speaker's target audience. Such presentations are ideal for individuals who prefer a text-heavy presentation as well as those who enjoy a presentation that uses an abundance of images.
