PowerPoint, which actually was originally called "Presenter," started with a noble enough purpose. The tool was designed to provide users an easy way to create visual aids to communicate information more easily, quickly, and effectively than possible before.
Some of you may remember a time when it was a serious chore to put together a presentation. Ultimately you had to rely on
transparencies displayed on an overhead projector. You had the choice of drawing them freehand, ahead of time, or live; if you wanted to get really fancy you could type them or print a diagram which could be transferred to transparencies using special transfer paper and special equipment. This process took a lot of time, was messy, and provided mixed results based on the skills, artistic prowess, penmanship, and organization of the presenter. PowerPoint provided a powerful new metaphor to make the process easier.
