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. Towards the mid-1980s, however, things began to change. as improving technology allowed the production of cheaper bitmapped displays, and 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.
