Death by PowerPoint is a phenomenon caused by the poor use of presentation software.
Key contributors to death by PowerPoint include confusing graphics, slides with too much text and presenters whose idea of a good presentation is to read 40 slides out loud. Death by PowerPoint is easily recognized by observing the audience members' glazed eyes, furtive use of smartphones and trips to the bathroom.
When an audience remains emotionally disconnected from the content that is being presented, there is a good chance that the speaker has either not spent enough time and effort thinking about which key points he wants the audience to take away -- or he has spent entirely too much time and effort setting up the presentation in PowerPoint, incorporating every feature and display option the software provides. Death by PowerPoint can be avoided if the speaker uses the technology as a visual aid to enhance what is being said, instead of relying on the technology to serve as the focus of the presentation.
