PowerPoint
was created by Robert
Gaskins and Dennis
Austin at a
software startup in Silicon
Valley named Forethought,
Inc. Forethought
had been founded in 1983 to create an integrated environment and applications
for future personal computers that would provide a graphical user interface,
but it had run into difficulties requiring a "restart" and new plan.

The
earliest version of PowerPoint (1987 for Macintosh) could be used to print
black and white pages to be photocopied onto sheets of transparent film for projection from overhead
projectors, and to print speaker's notes and audience handouts; the next version
(1988 for Macintosh, 1990 for Windows) was extended to also produce color 35mm slides by communicating a file over a modem to
a Genigraphics imaging center with slides returned by overnight
delivery for projection from slide
projectors. PowerPoint
was used for planning and preparing a presentation, but not for delivering it
(apart from previewing it on a computer screen, or distributing printed paper
copies). The operation of PowerPoint changed substantially in its third
version (1992 for Windows and Macintosh), when PowerPoint was extended to also
deliver a presentation by producing direct video output to digital
projectors or
large monitors.
I purchased
P-2 computer for my 11 years old daughter who opened her first ever Hotmail
account in 1997 and I typed my life’s first ever article in MS Word in 2005 on
the same computer.
