Brian Kelly's UK Web Focus blog tells me that, for better or worse, PowerPoint has been with us for 25 years. 25 years of PowerPoint. But What Next? I'm surprised. I first came across computer presentation software in the early 1990s, while working in the NHS, where the package of choice was a thing called Harvard Graphics. Many was the happy afternoon I spent in the GP Tutors office upstairs in the Postgraduate Centre at Edgware General Hospital, trying to beat pie charts into shape. Harvard Graphics ran slowly, if it ran at all. Non-conformists that we were, we used WordPerfect for word-processing and Lotus 1-2-3 for spreadsheets. I think I came under the thrall of Mr Gates later om the 1990s.
