PowerPoint is still one of the most common tools
A PowerPoint presentation is still one of the preferred tools for conveying messages. It is a widely used format, available to everyone, and it offers graphic support to your speech.
An effective presentation engages your audience
Words are a powerful tool, but words combined with images multiply their effect. The human mind not only prefers visual content, it processes it sixty thousand times faster. Using the right images and associating them with the concepts you want to highlight lets you show the quality of your ideas to the audience.
By using a PowerPoint presentation you have control on the content
An effective PowerPoint presentation lets you follow the thread of the speech, elaborate the concepts without boring the listener, and avoid getting lost in long, generic speeches. It allows you to decide how and when to bring value to your speech.
