Aldus practically invented Desktop publishing with "PageMaker".

WordPerfect and Word are lower in functionality but less
expensive and exist on both DOS and Macintosh (WordPerfect
on UNIX too).  These are essentially word-processing packages
rather than Desktop Publishing.  WordPerfect and Word are
by far the most popular with millions of copies sold.

See comp.text.desktop for more information. Interleaf
and FrameMaker are workstation-based and are higher in
price and functionality, and require more substantial
machine resources, but give you more in return.  FrameMaker
is now available for Windows 3.1, giving transportability
between the DOS/Windows, Mac and UNIX world.  See comp.text.desktop,
comp.text.frame and comp.text.interleaf.
