Mitch Kapor had written a statistical analysis and data graphing program for the Apple II called TinyTROLL, which he sold through a partnership with his friend and then MIT finance PhD student Eric Rosenfeld who had suggested the program to Kapor. The partnership was called Micro Finance Systems, and Kapor was approached VisiCorp to adapt TinyTROLL to work with data imported from VisiCalc. Kapor soon delivered VisiPlot and VisiTrend, programs that took VisiCalc spreadsheet data and generated pie, bar, and line graphs from them, as well as performed various finance-relevant statistical functions on the data. Kapor and Rosenfeld’s Micro Finance Systems received hundreds of thousands of dollars in royalties for VisiPlot and VisiTrend before VisiCorp bought them outright for $1.2 million. With his share in the windfall, Kapor set up an integrated software manufacturer of his own, Lotus Development, and, in 1982, the firm released its first product, Executive Briefing System, for the Apple II. Todd Agulnick, a 14-year-old high school student, had been hired by Kapor and wrote the BASIC code for Executive Briefing System under his direction.9Note
Lotus’ $200 Executive Briefing System was centered on the color video display of the Apple II. In brief, a number of programs for charting and graphing like VisiPlot offered the “BSAVE” command. Instead of routing data to immediately render an image on the video display, BSAVE sent the very same data to a stored file. In this way, a “screen shot” could be rendered on the video display at a later time, shared with others, archived for future use, etc. Lotus’ Executive Briefing System treated BSAVE’d files—these screen shots—as “slides” that could be modified and then displayed on the Apple II’s video display as a “slide show” for a “presentation.” Executive Briefing System users could edit slides of charts and plots by adding text and/or clip art of lines, geometric shapes, or “ornamental” motifs. Slides were arranged in slide shows, and saved to floppy disk. While the program allowed a slide show to be printed—as a paper report or for transparencies for overhead presentation—it focused on slide shows for the video display. A variety of animated “transitions” between slides were available, such as fades, wipes, and spinning-into-view.
