PageMaker is a desktop publishing software developed by Aldus Corporation in the 1980s. It allows users to create professional-quality documents, such as brochures, newsletters, and magazines, by combining text and images in a visually appealing layout. The software was one of the first to use the WYSIWYG (What You See Is What You Get) interface, making it easier for users to see how their final product would look while they were designing it. In 1994, Adobe Systems acquired Aldus Corporation and continued to develop PageMaker. Although it was popular for many years, it eventually faced competition from other software like Adobe InDesign and was discontinued in 2004. Despite this, PageMaker played a significant role in the evolution of desktop publishing and influenced many modern design tools.
