Microsoft PowerPoint is the world's most common presentation tool. It emerged from software company Forethought Inc in the 1980s. Bob Gaskins was the man behind it.
"I knew in the early 80s that there were as many as a billion, a thousand million presentation slides being made per year just in America," Gaskins says, but they were all made by hand and almost nobody was using computers to do them.
"It was clear to me that here was a huge application worth billions and billions of dollars a year that could be done on computers as soon as there was a revolution in the kinds of computers that we had."
Gaskins was onto something, but it was a hard sell at the time. The software wouldn't run on any existing personal computers. Anyone wanting to use it had to buy a new machine. Even so, people bought personal computers for the first time in order to be able to use PowerPoint, says Wired magazine journalist Russell Davies.
Davies explains that before PowerPoint, people used slides to convey information to groups — but anyone creating a presentation had to send away to get their materials made. It took a long time to do, was difficult to make changes and because it was so expensive, only the most senior people in an organisation got to do it.
"PowerPoint," Davies says, "made it possible for everyone in an organisation to stand up and say their piece."
PowerPoint has helped turn us all into presenters — but it' s also been accused of over-simplifying ideas and distracting (干扰)us from clear thinking.
Sarah Kaplan is a management professor at the University of Toronto's Rotman School of Management. She has noticed that, rather than people asking for new analysis or insights in meetings, they were asking for more PowerPoint slides.
Kaplan says that some CEOS, such as Amazon's Jeff Bezos, have banned its use. "He felt, and I think many people feel, that PowerPoint became such an object of the process that they lost the ideas inside of it and that is the risk."
