Theme: Presenting the information through the PPT
Have you ever had to give a presentation? What tool did you use? Perhaps it was Microsoft Power Point? If you did, you weren't alone. Around 30 million presentations are created each day using it. But who invented this program and what is its future? PowerPoint was originally called Presenter and it was the creation of Robert Gaskins and Dennis Austin. In 1987, when it first became available, only Apple Macintosh users had access to it. The program was bought by the Microsoft Corporation in July of the same year. When PowerPoint was developed, it was created for people in business. Since then it has been used in schools, universities, hospitals, offices and conferences. It is used not only to give presentations, it is also used to present data, analyze information, edit photos and do sums. It is a versatile tool that allows users to present images, texts and graphs.
The information can be made more entertaining by adding sounds or visual effects, e.g. the text can appear word by word or from the side. What made PowerPoint so successful? The first thing is that it was easy to use. It's clear icons on buttons and dialogue boxes, the screens and
slide designs. Individual slides meant that each one could project a different idea. In addition, the fact that each slide could contain images and texts made it a very powerful tool. Microsoft continues to improve PowerPoint, and some of the features from the 2019 version include inserting a 3D model which can be rotated 360º; easily removing the background from photos, recording video or audio and some special effects. The most interesting tools are the improved AI (artificial intelligence) features: PowerPoint Coach and PowerPoint Designer. The coach gives suggestions while the user practises his or her presentation in front of the computer. PowerPoint Designer helps generate slides and ideas. It helps to create layouts that are well designed. With new apps and programs being invented every day, it will be interesting to see what PowerPoint will be like in the future. Will people continue to use it, or will there be a better presentation tool on the market?
