Key takeaways

  • Microsoft PowerPoint belongs to computer science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Microsoft PowerPoint to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Microsoft PowerPoint from memory before moving on to harder problems.

Reference excerpt

Microsoft PowerPoint, or simply PowerPoint, is a presentation program developed by Microsoft. It was originally created by Robert Gaskins, Tom Rudkin, and Dennis Austin at a software company named Forethought, Inc. It was released on April 20, 1987, initially for Macintosh computers only. Microsoft acquired PowerPoint for about $14 million three months after it appeared. This was Microsoft's first significant acquisition, and Microsoft set up a new business unit for PowerPoint in Silicon Valley where Forethought had been located. PowerPoint became a component of the Microsoft Office suite, first offered in 1989 for Macintosh and in 1990 for Windows, 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. 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. Since the late 1990s, PowerPoint's worldwide market share of presentation software has been estimated at 95 percent. PowerPoint was originally designed to provide visuals for group presentations within business organizations, but has come to be widely used in other communication situations in business and beyond. The wider use led to the development of the PowerPoint presentation as a new form of communication, with strong reactions including advice that it should be used less, differently, or better. The first PowerPoint version (Macintosh, 1987) was used to produce overhead transparencies, the second (Macintosh, 1988; Windows, 1990) could also produce color 35 mm slides. The third version (Windows and Macintosh, 1992) introduced video output of virtual slideshows to digital projectors, which would over time replace physical transparencies and slides. A dozen major versions since then have added additional features and modes of operation and have made PowerPoint available beyond Apple Macintosh and Microsoft Windows, adding versions for iOS, Android, and web access.

History

Creation at Forethought (1984–1987) 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. On July 5, 1984, Forethought hired Robert Gaskins as its vice president of product development to create a new application that would be especially suited to the new graphical personal computers, such as the Apple Macintosh and later Microsoft Windows. Gaskins produced his initial description of PowerPoint about a month later (August 14, 1984) in the form of a 2-page document titled "Presentation Graphics for Overhead Projection." By October 1984, Gaskins had selected Dennis Austin to be the developer for PowerPoint. Gaskins and Austin worked together on the definition and design of the new product for nearly a year, and produced the first specification document dated August 21, 1985. This first design document showed a product as it would look in Microsoft Windows 1.0, which at that time had not been released. Development from that spec was begun by Austin in November 1985, for Macintosh first. About six months later, on May 1, 1986, Gaskins and Austin chose a second developer to join the project, Thomas Rudkin. Gaskins prepared two final product specification marketing documents in June 1986; these described a product for both Macintosh and Windows. At about the same time, Austin, Rudkin, and Gaskins produced a second and final major design specification document, this time showing a Macintosh look. Throughout this development period, the product was called "Presenter". Then, just before release, there was a last-minute check with Forethought's lawyers to register the name as a trademark, and "Presenter" was unexpectedly rejected because it had already been used by someone else. Gaskins says that he thought of "PowerPoint", based on the product's goal of "empowering" individual presenters, and sent that name to the lawyers for clearance, while all the documentation was hastily revised. Funding to complete development of PowerPoint was assured in mid-January 1987, when a new Apple Computer venture capital fund, called Apple's Strategic Investment Group, selected PowerPoint to be its first investment. A month later, on February 22, 1987, Forethought announced PowerPoint at the Personal Computer Forum in Phoenix; John Sculley, the CEO of Apple, appeared at the announcement and said "We see desktop presentation as potentially a bigger market for Apple than desktop publishing." PowerPoint 1.0 for Macintosh shipped from manufacturing on April 20, 1987, and the first production run of 10,000 units was sold out.

Acquisition by Microsoft (1987–1992) By early 1987, Microsoft was starting to plan a new application to create presentations, an activity led by Jeff Raikes, who was head of marketing for the Applications Division. Microsoft assigned an internal group to write a specification and plan for a new presentation product. They contemplated an acquisition to speed up development, and in early 1987 Microsoft sent a letter of intent to acquire Dave Winer's product called MORE, an outlining program that could print its outlines as bullet charts. During this preparatory activity Raikes discovered that a program specifically to make overhead presentations was already being developed by Forethought, Inc., and that it was nearly completed. Raikes and others visited Forethought on February 6, 1987, for a confidential demonstration. Raikes later recounted his reaction to seeing PowerPoint and his report about it to Bill Gates, who was initially skeptical:

Worked examples

Example 1 — a first encounter with Microsoft PowerPoint

Start with the simplest possible case. Write down what Microsoft PowerPoint claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Microsoft PowerPoint before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Microsoft PowerPoint ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Microsoft PowerPoint

In research
Microsoft PowerPoint appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Microsoft PowerPoint in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Microsoft PowerPoint is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1987 software, Brands that became generic, Microsoft Office, so understanding it makes those chapters shorter.
In everyday life
Look for Microsoft PowerPoint outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
