History computer presentations

The history of the development of computer presentations can be reviewed on the example of such a software product like Microsoft Power Point that is most commonly used for this purpose. It was originally named Presenter. The program was created by two students who felt that it was time to look for new ways of presenting information.

Initially, the program worked only in black-and-white mode, and was then developed her color version. This was published quite a weighty Tome that contained detailed guidance on the use of the program. But since this idea was quite expensive, it was soon discarded.

Over time, the program was adapted to different operating systems and got all the new features. Appeared animation features, bindings, hyperlinks and more. Following the concept of this product, computer presentation is a document that is perceived as a single set of slides, not a set of separate files.
