Adobe PageMaker (formerly Aldus PageMaker) is a discontinued desktop publishing computer program introduced in 1985 by the Aldus Corporation on the Apple Macintosh.[1] The combination of the Macintosh's graphical user interface, PageMaker publishing software, and the Apple LaserWriter laser printer marked the beginning of the desktop publishing revolution. Ported to PCs running Windows 1.0 in 1987,[2] PageMaker helped to popularize both the Macintosh platform and the Windows environment.[3][4]
