PowerPoint was released in April 1987. This was before Windows was a thing. It was actually released on the Macintosh first. Photoshop was released shortly after in 1988. I started using PowerPoint in 1989 and it has been a firm favourite ever since. Microsoft has continued to develop its features and because it is a stable part of the IT landscape in almost all education jurisdictions, not to mention workplaces, it is fair to say that if you create a file using PowerPoint it will be able to be read by whoever you send it to.
So what is my confession?
