as a direct descendant of it. In late 1978, in parallel with but independent of the work at Xerox PARC, Hewlett Packard developed and released the first commercial WYSIWYG software application for producing overhead slides (or what today are referred to as presentation graphics). The first release, named BRUNO (after an HP sales training puppet), ran on the HP 1000 minicomputer, taking advantage of HP 2640—HP's first bitmapped computer terminal. BRUNO was then ported to the HP-3000 and re-released as "HP Draw". By 1981, MicroPro advertised that its WordStar word processor had WYSIWYG, but its display was limited to displaying styled text in WYSIWYG fashion; bold and italic text would be represented on screen, instead of being surrounded by tags or special control characters. In 1983, the Weekly Reader advertised its Stickybear educational software with the slogan "what you see is what you get", with photographs of its Apple II graphics, but home computers of the 1970s and early 1980s lacked the sophisticated graphics capabilities necessary to display WYSIWYG documents, meaning that such applications were usually confined to limited-purpose, high-end workstations (such as the IBM Displaywriter System) that were too expensive for the general public to afford. As improving technology allowed the production of cheaper bitmapped displays, WYSIWYG software started to appear in more popular computers, including LisaWrite for the Apple Lisa, released in 1983, and MacWrite for the Apple Macintosh, released in 1984. The Apple Macintosh system was originally designed so that the screen resolution and the resolution of the ImageWriter dot-matrix printers sold by Apple were easily scaled: 72 PPI for the screen and 144 DPI for the printers. Thus, the scale and dimensions of the on-screen display in programs such as MacWrite and MacPaint were easily translated to the printed output. If the paper were held up to the screen, the printed image would be the same size as the on-screen image, but at twice the resolution. As the ImageWriter was the only model of printer physically compatible with the Macintosh printer port, this created an effective closed system. Later, when Macs using external displays became available, the resolution was fixed to the size of the screen to achieve 72 DPI. These resolutions often differed from the VGA-standard resolutions common in the PC world at the time. Thus, while a Macintosh monitor had the same 640 × 480 resolution as a PC, a screen would be fixed
