What are used of MS PowerPoint​

Microsoft PowerPoint is a presentation program,[6] created by Robert Gaskins and Dennis Austin[6] at a software company named Forethought, Inc.[6] It was released on April 20, 1987,[7] initially for Macintosh System Operating system based computers only.[6] Microsoft acquired PowerPoint for about $14 million three months after it appeared.[8] This was Microsoft's first significant acquisition,[9] and Microsoft set up a new business unit for PowerPoint in Silicon Valley where Forethought had been located.[9]

PowerPoint became a component of the Microsoft Office suite, first offered in 1989 for Macintosh[10] and in 1990 for Windows,[11] which bundled several Microsoft apps. Beginning with PowerPoint 4.0 (1994), PowerPoint was integrated into Microsoft Office development, and adopted shared common components and a converged user interface.[12]

PowerPoint's market share was very small at first, prior to introducing a version for Microsoft Windows, but grew rapidly with the growth of Windows and of Office.[13](pp402–404) Since the late 1990s, PowerPoint's worldwide market share of presentation software has been estimated at 95 percent.[14]

PowerPoint was originally designed to provide visuals for group presentations within business organizations, but has come to be very widely used in many other communication situations, both in business and beyond.[15] The impact of this much wider use of PowerPoint has been experienced as a powerful change throughout society,[16] with strong reactions including advice that it should be used less,[17] should be used differently,[18] or should be used better.[19]

The first PowerPoint version (Macintosh 1987) was used to produce overhead transparencies,[20] the second (Macintosh 1988, Windows 1990) could also produce color 35 mm slides.[20] The third version (Windows and Macintosh 1992) introduced video output of virtual slideshows to digital projectors, which would over time completely replace physical transparencies and slides.[20] A dozen major versions since then have added many additional features and modes of operation[12] and have made PowerPoint available beyond Apple Macintosh and Microsoft Windows, adding versions for iOS, Android, and web access.[citation needed]

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
