这是1984年，电脑科学家Robert Gaskins和Dennis Austin似乎给自己定了一个不可能完成的任务。
They are attempting to bring the old-fashioned projector slide into the 20th century by building a piece of software that allows users to present ideas from their computers. After a few false starts, the fledgling entrepreneurs are successful, and on the April 20, 1987, their opus goes sale.
他们试图通过开发一个软件，将老式的投影片引入到20世纪，以便用户能在电脑上展示他们的想法。经过几次错误的尝试，两位羽翼未丰的创业者成功了，1987年4月20日，他们的作品开始出售。
The software becomes an instant success, making $1m (or $2.18m in modern money) in its first month. Born in California, the programme has gone on to achieve global acclaim with 1bn copies sold. And today, PowerPoint will celebrate its 30th birthday – one of the very few apps to achieve longevity of this kind.
这个软件迅速获得成功，发布第一个月便赚了100万美元（约相当于现在的218万美元）。诞生于加利福尼亚，该项目已经获得了全球赞誉，售出了10亿份。如今，PowerPoint将庆祝其三十岁生日——极少数应用程序能有如此长的生命周期。
