In 1987, Microsoft launched PowerPoint
and the digital presentation began. Companies began to use them for
their presentations. Keeping an audiences attention was much easier.
Soon sound, graphics, and videos were able to be added to the
presentation. Teachers who used them in the classroom could keep
students engaged easier.
Moving to 2013 the top presentations are easy to create and include animations. Prezi, Go Animate, Google Docs, Slide Rocket, SoHo Show, and Slide Snack are 6 of the best presentation software alternatives from PowerPoint.
