The Improbable Origins of PowerPoint

David Brock:

With PowerPoint as well as its predecessors, the motif of the slide was, of course, lifted directly from the world of photography. Some presentation programs actually generated 35-mm slides for display with a slide projector. In most cases, though, the early programs created slides that were printed on paper for incorporation into reports, transferred to transparencies for use on overhead projectors, or saved as digital files to be displayed on computer monitors.

The upshot was that personal computer users of the 1980s, especially business users, had many options, and the market for business software was undergoing hypergrowth, with programs for generating spreadsheets, documents, databases, and business graphics each constituting a multimillion-dollar category. At the time, commentators saw the proliferation of business software as a new phase in office automation, in which computer use was spreading beyond the accounting department and the typing pool to the office elites. Both the imagined and actual users of the new business software were white-collar workers, from midlevel managers to Mahogany Row executives.

PowerPoint thus emerged during a period in which personal computing was taking over the American office. A major accelerant was the IBM Personal Computer, which Big Blue unveiled in 1981. By then, bureaucratic America—corporate and government alike—was well habituated to buying its computers from IBM. This new breed of machine, soon known simply as the PC, spread through offices like wildfire.
